MARKING WEB MATERIAL Emile Bernard Bates, Leicester, England ApplicationFebruary 21,

In Great Britain 6 Claims.

This invention concerns marking machines for marking Web material such for example as knitted or other fabric in the piece and its chief object is an improved marking apparatus for use in such machines.

The invention provides in or for a marking machine for marking web material, marking apparatus comprising a hollow rotatable web-engaging roller or wheel having, mounted to rotate with it, an electric iron mounted for projection to and retraction from an operative position in which it is presented at the periphery of the roller, a mounting for a wound supply of marking ribbon and a take-up means for accumulating the used ribbon, guides for guiding the ribbon from the supply to the take-up means in a path which presents it to be pressed against the web by the projected iron, feed mechanism for feeding the ribbon step by step from the supply to the take-up means the feed taking place upon the retraction of the iron, and mechanism for projecting and retracting the iron. This apparatus has the advantage that it permits the employment of a ribbon which is coated or otherwise treated uniformly along its surface in such manner that, when pressed by the heated iron against the fabric or the like, a mark is applied to the fabric. Therefore the correct and unfailing application for the mark is not dependent upon the accurate register of any given area on the ribbon with the iron at the time that the iron ispresented to the fabric and therefore the ribbon feeding arrangements are of a simple character. Furthermore, since the accurate operation of the apparatus is independent of an such registration requirements, the apparatus is suitable for the application of a mark to the web at predetermined linear intervals the linear intervals being for example predetermined by the circumferential dimension of the roller or wheel.

The foregoing and other features of the invention defined in the appended claims are incorporated in the marking machine which will now be described, as a preferred example, with referencev to the accompanying drawings in which Figures 1, 2 and 3 are respectively a perspective view, a side elevation, and a front elevation of the machine;

Figures 4 and 5 are side elevations of the marking drum on a larger scale and partly in section, illustrating its operation;

Figure 6 is a sectional elevation of the drum looking towards the delivery end of the machine;

Figure 7 is a front elevation, partly in section, of the iron and adjacent parts, and Figure 8 is a side elevation thereof;

In one construction'of marking machine the fabric or otherweb l to be marked is fed over a table 2 by engagement in the nip between a lower feed roller 3 and an upper marking drum e and is accumulated on a roll 5 which is driven by the engagement of a driving roller 6 with the I on the roll. The driving roller 6 is geared to the marking drum 4, the gearing being shown as chain and sprocket gearing. The shaft 1 of drum 4 is provided with a crank handle 8 by which it may be turned and is geared in the ratio 1 to l to the shaft 9 of the bottom drum 3 by chain I 0 running over sprockets H, l2, l3, l4. Shaft 9 is geared to roller 6 by chain l5 running over sprockets 16, ll, I8. The web 1 is drawn from a supply roll l9 removably supported on wheels 20, and runs over guide roller 2,! to the nip. Take up roll 5 has the ends of its shaft 22 removably received in channelled guides 23.

The foregoing parts are mounted on a suitable inactive frame, indicated at 2 4, in a manner that will readily be appreciated from the drawing. It will also be appreciated that thedriving power is not necessarily applied from the drum shaft 7 and may be derived from an electric motor or line shafting.

The marking drum 4 has a window 25 cut in its periphery at one location and carries inside it an electricallyheated iron 26 mounted in guides 27 to reciprocate towards and away from the window. 'The iron 26 is reciprocated by means of an ccentricstrap 28 which is pivotally connected to it at 29 and encircles a stationary eccentric .30. Thus at each rotation of the drum 3 the iron 26 is projected and then retracted and the eccentric 33 is so disposed that the iron occupies its'projccted position as it reaches the nip (Fig. 5). Within the window 25 there is a flexible ribbon-supporting plate 35 which, as best shown in Figs. 4. and 5, conforms in side elevation to theperiphery of the drum 4. The plate 35 is mounted (as a cantilever) at one end, at 3%, and its other end rests on an abutment 3i the mounting 35 and the abutment 3'! are spaced inwards of the ends of the window 25 so as to have gaps or slots 38, 39. and the plate 35 is cut out at til to the shape of the iron 26.

Also mounted within the drum ii there is a spindle 3| for receiving a spool 32 of marking ribbon 33, and a spool 34 on which the used ribbon is accumulated, and parts 35, 31 which serve as guides for guiding the ribbon 32 from the supply spool 32 to the take-up spool 34 in a path which extends through the slots 38, 3E} and over the plate 35. Thus the path extends across the windows 25, 116, so that each time the iron 26 is projected it presses a portion of the ribbon 33 against the fabric 1 as shown on Fig. 5.

The take-up spool 34 is driven by the engagement of a rubber-covered driving roller 4! with the periphery of the accumulated wound package of used ribbon, and this driving roller 4| is given a movement of partial rotation each time the iron is reciprocated. The movement of partial rotation is produced by means of pawl-andratchet or free-wheel mechanism, operated in each revolution of the marking drum. For example, the driving roller All may be driven by pawl-and-ratchet mechanism or free-wheel mechanism 42 from a rotatable driver 43 over which a chain or other flexible element 44. is passed, one end of the element 44 being connected to a tension spring 45 and the other end to a lever 46 which is rocked at each revolution of the marking drum 4 by a cam 41 disposed alongside the eccentric 30. The spring 45 is anchored in at 48 and the lever 46 is pivoted at 49. Thestroke of the lever 41, and therefore the length of ribbon wound up at each operation, is regulated by adjustment screw 50. Eccentric 39 and cam 41 are carried on a sleeve 5| and if they are stationary, then the ribbon 33 is fed once at each revolution of the drum, so that a mark is applied to the fabric 1 at each revolution. It may be desired to apply a mark every second, third, etc., revolution, and this effect is achieved by driving at the appropriate speed reduction (e. g., 2 to l, and 3 to 1) relative to the drum 4. A simple mechanism for doing this is shown in Fig. 9. Drum shaft 1 is geared to sleeve 52 by reduction gearing shown as consisting of hub 52, sprocket 53 on shaft 1, sprockets 54, 55 on hub 52, sprocket 56 on sleeve 58 (connected to sleeve 5|) and chains 50, 60.

As will readily be appreciated, the outer face of the iron 26 is curved so that when the iron is projected this face conforms to the peripheral surface of the drum d. The outer face may carry any suitable marking (in relief) which it is desired to apply by means of the ribbon 33 to the fabric or the like I and certain or all of this marking may be carried by a member which is capable of being indexed so as to present differing data or characters (e. g. numerals indicative of length) at the outer face of the iron. For example, part of tuted by a wheel or wheels having numeralsaround its periphery the said wheel being stepped round each time the iron is reciprocated so that successive numerals are presented at the face of the iron in their numerical order. Thus in Figs. 7 and 8, two numbered wheels BI, 62 are rotatably mounted on spindle 63 and are provided with ratchet wheels 64, 65 which are racked round by stationary spring loaded pawls 66, iii each time the iron is retracted. Spring loaded detent mechanism 68, 69 is provided for retaining the wheels in each position to which they are turned, and the wheels derive heat from the main body of the iron 26, which is electrically heated by means of a resistance heating element in a manner requiring no illustration. The leads in, H are fed by way of brush apparatus 12 and a switch '13.

The take-up spool 34 is that a full spool may be one. For this purpose, on the ends of levers 14a,

readily detachable, so replaced by an empty the spool is supported 1422 which pivot on the eccentric 39 and cam 41.

the iron may be constithe sleeve 51 and are provided with tension springs 15a, 151) which normally urge the spool 34 against the roller 4|. If the levers are moved against the spring tension, the spool may readily be lifted out through the open end of the drum 4. This lever movement is produced by cams 16a, 16b operable manually by a crank 11.

The machine may be provided with a counting appliance 1,8 for recording or showing the numher of revolutions made by drum 4.

The ribbon 33 may consist of a thin paper base with a wax coating at one face; a coating of metal powder is stuck to this wax coating and itself is coated with a thermoplastic adhesive (such for example as rubber or gutta percha) which only becomes tacky on the application of heat. It is the adhesiveface which is pressed by the iron 26 against the fabric or other web I, so that areas of the adhesive corresponding to the relief marking on the iron are melted and transferred to the web together with the registering areas of metal powder.
