Definitions
- the present invention relates to an apparatus for conveying a web of material in the machine direction while continuously stretching or releasing stretching forces from the web in the cross-machine direction.
- Tentering equipment usually consists of a series of spring loaded clamps attached to a pair of opposing carrier chains. These chains are adjustable in width to provide a desired amount of stretch so as to increase the width of the material.
- these clamps are discrete and discontinuous and produce high stresses in the web material adjacent to the clamping area. This would often cause the web material to rip or tear during the manufacturing process.
- V-belts such as the one disclosed in the herein incorporated reference, use two pairs of belts having V-shaped cross-sections wherein the flat part of the belts make contact with the web of material in order to convey it.
- this type of apparatus will not adequately stretch webs in the cross- machine direction because the belts do not provide sufficient gripping force to hold onto the web. Consequently, the web of material would have a tendency to slip off of the belts resulting in costly shut down time.
- an apparatus for conveying a web is able to continuously stretch the web in the cross-machine direction.
- the apparatus includes two pairs of opposing belts wherein each belt travels along an endless path. The pairs of belts diverge from each other in the cross-machine direction.
- Each pair of belts comprises an upper belt and a lower belt which are adjacent to each other.
- Each of the upper and lower belts has a non-planar outer surface for contacting the web.
- the non-planar outer surfaces of each upper belt continuously abuts the non-planar outer surface of its adjacent lower belt along a predetermined distance when traveling in the machine direction. This creates at least one nip for continuously gripping the web while it is being conveyed.
- the apparatus also includes a means for driving the belts so as to convey the web in the machine direction.
- an apparatus for conveying a web wherein the apparatus is able to continuously release stretching forces from a web.
- the apparatus has two pairs of opposing belts wherein each belt travels along an endless path. The pairs of belts converge towards each other in the cross machine direction.
- Each pair of belts comprises an upper belt and a lower belt which are adjacent to each other.
- Each of the upper and lower belts has a non-planar outer surface for contacting the web.
- the non-planar outer surfaces of each upper belt continuously abuts the non-planar outer surface of its adjacent lower belt along the predetermined distance when traveling in the machine direction. This creates at least one nip for continuously gripping the web.
- the apparatus also has a driver for driving the belts so as to convey the web in the machine direction.
- Figure 1 is a plan view of an apparatus in accordance with the present invention.
- Figure 2 is a side view of the apparatus in accordance with the present invention.
- Figure 3 is a cross-section of the apparatus of Figure 1 taken along lines 3- 3.
- Figure 4 is a view similar to Figure 3 but showing belts 21 and 22 up close.
- Figure 5 is a plan view of an alternative embodiment of an apparatus in accordance with the present invention.
- Figure 6 is a plan view of yet another alternative embodiment of an apparatus in accordance with the present invention.
- FIG. 1 a plan view of an apparatus 1 for continuously stretching a web 10 in accordance with the present invention.
- Apparatus 1 conveys web 10 in the machine direction, indicated by arrow 2, and stretches the web in the cross-machine direction, indicated by arrow 3.
- apparatus 1 comprises two pairs of opposing belts 21, 22 and 31, 32.
- each belt travels along an endless path, and as seen from Figure 1 again, the pairs of belts 21, 22 and 31, 32 diverge from each other in the cross-machine direction 3, at any desired angle such as 30°, depending on various factors such as the material to be stretched and the amount of stretch desired.
- the apparatus 1 can better be explained by referring to Figure 3 which is a cross-section of Figure 1 taken along line 3-3.
- the apparatus comprises two upper belts 22 and 32 and two lower belts 21 and 22.
- Upper belt 22 is adjacent lower belt 21 and upper belt 32 is adjacent lower belt 3 1.
- Each of the upper and lower belts has a non-planar outer surface 21a, 22a, 31a and 32a for contact with web 10.
- the non-planar outer surface of each upper belt, 22a and 32a substantially continuously abuts the non-planar outer surface of its adjacent lower belt, 21a and 31a respectively, along a predetermined distance in the machine direction.
- non-planar outer surfaces of belts 21 and 22 As will be discussed below, the abutting relationship between the non-planar outer surfaces of belts 21 and 22 and those of 3 I and 32 create nips for gripping web 10 along its outer edges.
- the non-planar outer surfaces of belts 21, 22, 31 and 32 are shown in the figures as having an outwardly disposed triangular shape, however, any number of non-planar surfaces can be used to create the nip.
- FIG. 4 The embodiment shown in the Figures can best be described by referring to Figure 4.
- two nip points 41 and 42 are created.
- the interference fit between these points is preferably from about 0.005 in. to about 0.015 in.
- a lateral force in the direction of arrow 60 is applied to belts 21 and 22 due to the web being stretched in the cross-machine direction.
- the tip of non-planar outer surface 22a moves allowing nip 42 to open somewhat.
- a counter clockwise rotation of belt 22 around point 43 occurs causing nip 41 to tighten and increase the interference fit.
- the distance from nip 42 to point 43 is roughly equal to the distance from nip 42 to nip 41 the increased nip pressure at 41 is proportional to the lateral force applied to the belts.
- belts 21 , 22, 31 and 32 are made from urethane, such as an A section "High Ridge Top” V-Belt manufactured by Eagle Urethane Belting Des Plaines, IL 60018.
- the belts cane be made from any suitable material known in the art including other thermosetting plastics.
- apparatus 1 has a series of substantially parallel rollers 50 which belts 21, 22, 3 1 and 32 travel around along their endless path. Rollers that are suitable for this purpose include 3 in. diameter glass reinforced nylon idlers for "A" section V-belts model #6234K43 available from the Efson Co., Wilmington, NC 28405. Other suitable rollers known to those skilled in the art can also be used.
- the apparatus 1 can also be used for continuously releasing stretching forces from an elastic web which has been stretched in the cross-machine direction.
- the only significant difference in the layout of the apparatus will be that the pairs of belts 21, 22 and 31, 32 will converge towards each other in the cross-machine direction instead of diverge from each other.
- the same apparatus can be used to initially stretch the web, and thereafter continuously release the stretching forces from the web.
- a plan view of such an apparatus is shown in Figure 5
- Figure 5 shows an apparatus 101 for conveying web 1 10 in the machine direction, indicated by arrow 102.
- Apparatus 101 is similar to apparatus 1 and comprises two pairs of opposing belts 121 (not shown), 122 and 131 (not shown), 132.
- Belt pairs 121, 122 and 131, 132 initially diverge in the cross-machine direction, indicated by arrow 103. Thereafter, the belts can then travel along parallel paths to convey the web further in the machine direction. Lastly, belt pairs 121, 122 and 131 , 132 begin to converge towards each other so as to release the stretching forces from the web.
- FIG. 6 Another alternative embodiment is shown in FIG. 6.
- apparatus 201 having 3 pairs of opposing belts wherein only the upper belts 212, 222 and 232 are shown.
- Apparatus 201 stretches web 210 at different rates as the web travels in the machine direction.
- Web 210 is stretched at a higher angle between belts 232 and 222, as indicated by arrow 204, than between belts 212 and 222 as indicated by arrow 204.
- Any number pf pairs of belts can be used to differentially stretch a web in this manner.
- the apparatus includes a driver or a means for driving the belts in the machine direction so they van convey the web in the machine direction.
- the driver is an "a" belt sheave model #AK64 manufactured by Browning Manufacturing, Maysville, KY 41056. While particular embodiments of the present invention have been illustrated and described herein it will be obvious to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the present invention and it is intended to cover in the appended claims all such modifications that are within the scope of this invention.
