Referringto the drawings in detail, there is shown in Fig. l a segment 10 of ornamental textile material which comprises a base. 12 formed of textile material, an ornamental element 14 of predetermined contour disposed on the outer surface 16 of said base, and a light permeable element 18 overlying said ornamental element, said elements collectively defining the spaced series of ornaments 20 disposed onthe'outer face of the textile material base. The elements 14 and 18 have continuous peripheral edge portions 22 and 24, respectively, which are heat sealed to each other in position .on the base 12 as shown in Fig. 8, said peripheral edge portion 22 being heat sealed to the continuous peripheral edge portion 26 of the securing element 28 which is disposed on the bottom surface 30, of the base 12. In the illustrated embodiment the. elements 14, 18 and 28 are formed of thermoplastic sheet material, for example vinyl plastic material, and the base 12 is formed of a suitable intersticed-textile material, the interstices of said textile material providing for the fiow of heated plastic material therethrough whereby to heat seal the assembly constituted by the elements 14 and 18 to the securing element 28 and thus to heat seal the ornaments 20 in position on the textile material base. Accordingly While fabric or textile material 12 is utilized as the base material of the illustrated and herein described embodiment, itwill be apparent that the present invention may be practiced by utilizing any suitable intersticed base material to provide for the flow of plastic material therethrough. The segment 10- of surface ornamented textile material is formed by the method tobe described in detail hereinafter.
The apparatus 32, shown in Fig. 3, utilized for the practice of the present invention, is conventional in the main and includes a head .34 mounted at the end of a vertically reciprocable ram 36, and a stationary bed 38., it being understood that the ram ismounted for vertical re ciprocation in any suitable manner whereby to vertically reciprocate the head 34 relative to its companion stationary bed 33. Mounted on the lower end of the head 34 in any suitable mannenis a die 40, which is best shown in Pig. 4, said die having a peripherally continuous raised vface 42 of preselected decorative outline, for example the outline of a dancing girl. As will be apparent from the description which follows, the die face 42 may be of any desired outline or contour corresponding to the desired contour of the ornaments 20 of the ornamented textile assembly 10,,the specific contours illustrated and described herein being given by way of example only. Thus the embodiment 10' illustrated in Fig. 2 (litters from the embodiment 10 of Fig. 1 only .in regard to the shape and disposition of the ornaments or ornamental elements .20 disposed on the textile base 12'. It will ac cordiugly be apparent thatthc ornaments or ornamental elements 2il and 20 may be of any desired shape or configuration and may be arranged on the surface of a textile base in any desired manner to achieve the desired ornamental effect. The die face 42 has a periphorally continuous edge portion 44 of an outline corresponding to the outline of said die face projecting from the outer sidecdgeof the latter, said projecting edge 42 is adapted to fuse or bond the plastic sheets 52 and 54 v to each other and to the plastic sheet 56 along the out line 58 corresponding to the outline of said peripheral edge by an electronic heat sealing operation, there being provided conventional electronic equipment-61 in the head 34 for this purpose. Accordingly the conventional electronic heat sealing equipment 61 is adapted to act through the die face 42 and, more particularly, the peripheral edge 46 thereof to effect an electronic heat sealing operation between the layers 52, 54 and 56 of plastic sheet material. The plastic layers 52-, 54 and 56 may be initially of determinate or indeterminate contour and are adapted to be contoured and heat sealed or fused by the apparatus 32 to form the elements 18, 14 and 28, respectively, the latter being initially integral portions of said plastic layers. In the practice of the present method the plastic sheets 52 and 54 are superposed on each other in overlying relation to the outer face 16 of the base 12 and the layer 56 is superposed on the opposite face 30 of said base, it being noted that the layers 52, 54 and 56 are in vertical registry. in the practice of the present method the registry between the layers 52, 54 and 56 is not critical, it being only necessary to provide for registry of the areas thereof which are to be bonded or heat sealed to each other. The base 12 may be of any desired determinate or indeterminate outline and may be formed of any desired threads or yarns. To effect a heat seal or bond between the layers 52. 54 and 56 and to secure the latter to the base 12 the ram 36 is reciprocated in a downward direction so as to reciprocate the die face 42 to the position shown in Fig. 6 in which said die face is effective to bond or fuse the plastic layers 52, 54 and 56 to each other along the peripherally continuous outline 58' corresponding to the outline of said die face. In the heat sealing or bonding operation the peripheral edge portions 22 and 24' of the layers 54 and 52, respectively, will be fused to each other along the outline 58' without the formation of a distinct line of demarcation between said edge portions and plastic material from said layers will flow through or penetrate the interstices of the textile base 12 to bond the layers 52 and 54 to the layer 56 along the peripheral edge portion 26' of the latter. Thus on the activation of the electronic equipment 61 the peripheral edge 46 of the die will sufficiently heat the plastic layers 52, 54 and 56 to cause a fusion thereof along the outline 58, this operation effecting the flow of plastic material through the interstices of the textile base 12 as shown in Fig. 8 whereby to effect a bond between the peripheral edge portions 22, 24' and 26' of the plastic layers. The edge portion 44 of the die face 42 projects beyond the edge 46 thereof to define the tear edges 48 and 50 along the outer edge of the bonded outline 53' of the ornamented textile assembly it!" simultaneous with the heat sealing of the plastic layers. From the above it will be apparent that the apparatus 32 is effecttive to bond the plastic layers 52, 54 and 56 to each other along peripherally continuous edge portions to provide a decorative outline 58 corresponding to the outline of the die face 42 and to simultaneously define the tear edges 48 and 50 on the opposite sides or faces of the base 12 of a corresponding configuration.
Subsequent to the above described bonding and contouring operation, the ram 36 is reciprocated upwardly as shown in Fig. 7 away from the work, to leave on the bed 38 the ornamented assembly which is in an intermediate stage of finish. The semi-finished assembly 10 is formed into a finished assembly or ornamented segment 1.0 by removing sheet material 60 and 62 of the layers 52 and 54, respectively, along the tear edge 48 and by removing sheet material 64 of the layer 56 along the tear edge 50, it being understood that the tear edge 48 is defined by plastic material of the layers 52 and 54 which fuse together during the above-described heat sealing and bonding operation. Thus the plastic sheet material 60 4 and 62, outside of the bonded and contoured area 66, may be readily removed from the assembly 10" by grasping a portion of said material and 62 and pulling the latter to separate it from said area 66 along the tear edge 48 (Fig. 9). Accordingly the operation of tearing or separating the material 60 and 62 from the bonded and contoured area 66 will result in the formation of a bonded plastic assembly having an outline corresponding to the outline of the die face 42 with the separated sheet material 60 and 62 having a cut out area 63 of corresponding outline, it being understood that sheet material 60 and 62 having such'a cut out area of pre selected decorative outline may be utilized in any desired manner, for example, for integration with other materials to form a decorative composite assembly. The sheet material 64 is similarly removed from the layer 56 along the tear edge 59 in the manner described above relative to sheet material 60 and 62 (Fig. 10), and this sheet material 64 having a cut out area 65 may be utilized in any desired manner. On the removal of the sheet material 60, 62 and 64 from the layers 52, 54 and 56, respectively, in the manner described above elements 53, 1.4 and 28, respectively, will be formed and said elements will be of the same contour or outline corresponding to the outline of die face 42. The finished ornamented textile segment 10, having ornaments 20 secured to one face thereof, may be utilized in any desired manner, for example for integration with other materials to form a decorative composite assembly. The element 18 may be formed of any suitable plain or ornamented plastic material and in the illustrated embodiment said element is transparent or translucent to reveal the ornamental element 14 positioned thereunder, said ornamental cl.- ment being colored if desired and having a plain or ornamented face 15.
It will be apparent that the ornamental assembly or segment 10 comprises segments or elements of plastic material 14 and 18 which are secured to the textile base 12, said base and said segments being free from direct connection to each other except along the bonded peripherally extending portion 23. Thus the segments or elements 14 and 18 are bonded and contoured at the same time in the same operation, said elements being secured to the outer face 16 of the base 12 by means of the securing element 28 disposed on the rear or inner face 30 of the base 12 and bonded to the elements 14 and 18 along the outline thereof. Since all of the constituent portions of the layers 52, '54 and 56 may be utilized it will be apparent that the technique described above is inherently very economical. While the ornaments 2i) and 20 of the illustrated embodiments are formed of two layers of plastic sheet material, it will be understood that said ornamnets may be formed of any number of layers up to the capacity of the apparatus 32 and it is accord ingly within the scope of the present invention to form ornamental elements 20 from one or more sheets of plastic material.
The ornamented fabric assembly 10 and 10 may be utilized in any desired application, for example in the formation of articles such as wallets, vanity articles and the like. It will be understood that the layers 52, 54 and 56 of plastic sheet material may be formed of the same material or may be formed of different compatible materials so that such materials will bond or fuse together in the aforedescribed manner.
While we have shown and described the preferred em bodiments of our invention, it will be understood that various changes may be made in the idea or principles of the invention within the scope of the appended claims.
