7 Claims. (Cl. 242-671) The present invention relates to a machine for Winding up a web of fabric.

In the production of fabric webs to final form, it is customary to apply to a fabric web a hem along one of the side edges, and then store the thus treated fabric web until it is desired to complete the manufacture of such treated web. This is usually effected by winding the above-described treated fabric on a core and then placing such core in a place of storage. In the wind-up devices as now proposed, the treated fabric by virtue of the hem along one of the side edges cannot be wound up in the form of a roll but is wound up in the form of a cone with an end portion overlying one of the end edges of the core. Fabric webs wound up in this manner require further handling before they can be subjected to the final steps of completing the production of a marketable web.

An object of the present invention is to provide a machine which enables a fabric Web having had a hem applied to one of the side edges to be wound upon a core in the form of a roll.

Another object of the present invention is to provide a machine in which a fabric web having had a hem applied to one of the side edges of varying widths may be wound up on a core in the form of a roll.

A further object of the present invention is to provide a machine which is positive in action, simple in structure, and commercially feasible.

These and other objects and advantages of the present invention will be fully apparent from the following description when taken in connection with the annexed drawings, in which:

Figure 1 is a plan View of the machine according to the present invention;

Figure 15 is an isometric view of the tensioning device shown in Figure 14; and

Figure 16 is a sectional view, on an enlarged scale, taken on the line 16-16 of Figure 15.

Referring in greater detail to the drawings in which like numerals indicate like parts throughout the several views, the web wind-up machine according to the present invention comprises a base 20 from which rises, adjacent the rear end thereof, a hollow box frame 22 to which is attached, on its upper face, an upstanding U-shaped support member 24. A horizontally disposed rotatable driven shaft 26 is journaled intermediate its ends in the legs of the support member 24 inwardly of the upper ends thereof. The legs of the support member are designated by the reference numerals 28 and 30 and exteriorly of the one leg 30 is an enlarged portion of the shaft 26, designated by the reference numeral 32 in Figure 7. A sleeve 34 is circumposed about the enlarged portion 32 of the shaft 26 and is connected to the shaft 26 for simultaneous rotary movement and for reciprocating movement in both directions on the shaft 26 responsive to the rotary movement of the shaft 26.

The means connecting the sleeve 34 to the shaft 26 for limited reciprocal movement thereon includes, as shown in Figures 3 through 6, inclusive, a cam member 36 detachably secured by a machine screw 38 to one end of the hub 40 of a pinion gear 42. The hub 40 is rotatably mounted on a stub shaft 44 having one end threaded into a threaded bore provided in a vertically disposed plate 46 which abuts the one leg 30 of the support member 24. A nut 48 on the adjacent end of the shaft 44 maintains the shaft 44 in its horizontally disposed position projecting inwardly of the plate 46.

Another plate 50 is arranged in face to face spaced relation with respect to the plate 46 and is secured to the support member leg 30 with a spacer element 52 therebetween. The plate is provided with a slot 54 in which is reciprocally mounted an arm 56 carrying a pin 58 on one end thereof and having its other end secured to the outer race of a bearing assembly 60 which has its inner race fixedly secured to the sleeve 34 adjacent one end of the latter.

The connecting means also includes a slot 62 formed in the shaft portion 32 and in which is slidable a single ball bearing 64 rotatably seated in a recess 66 provided in one side of the sleeve 34, as shown in Figure 7.

A web anchoring means is provided for adjustably and detachably securing an end portion of a web to the sleeve 34. Specifically, this means embodies a collar 68 attachable to and detachable from the sleeve 34, as by means of a set screw 69, and forming a stop for a winding core 70 circumposed about and fixedly engaged with the sleeve 34 with one end adjacent to the collar 68.

A tapering pin 72, shown in dotted lines in Figure 3, projects from the bearing assembly 60 and forms a means about which may be looped an end portion of a web of fabric, designated by the reference numeral 74. In Figure 8 is shown how the end portion of the fabric web 74 is looped around the pin 72 preparatory to forming on the web core 70 a row of the web 74.

The means for imparting rotational movement to the shaft 26 includes a cross shaft 76 journaled intermediate its ends in the box frame 22 and carrying thereon a sprocket 78. A chain 80 connects the sprocket 78 to another sprocket 82 mounted upon the output shaft 84 of a variable speed electric motor 86. Another sprocket 88 carried on the shaft 76 exteriorly of the frame 22 is connected by a chain 90 to a driven sprocket 92 rotatable on the portion of the shaft 26 exteriorly of the leg 28 of the support member 24.

A drive plate 94 is formed integrally with the sprocket 92 and is biased by means of a spring 96 into frictional engagement with the leather face 98 of a driven plate 100. The driven plate 100 is secured to the shaft 26. A worm gear 102 mounted upon the shaft 26 is in mesh with the gear 42 which is carried by the stub shaft and is connected by the arm 56 to the sleeve 34 to effect the reciprocating movement of the sleeve 34 on the shaft portion 32 responsive to the rotary movement of the shaft 26.

A web tensioning means, designated generally in Figures l to 4, inclusive, by the reference numeral is positioned in cooperating relatively constant spaced relation with respect to the laying of the web 74 on the sleeve 34- for placing the web under tension during the execution of the reciprocatory and rotary movement of the sleeve 34. The means 1% includes a plurality of spaced horizontally disposed bars 166 arranged invertical spaced relation, the bars being each of a length corresponding to the sleeve 34. Each of the bars 166 has one end rigidly supported in an upstanding plate 168 fixedly secured to the base 26 on the side of the latter remote from the drive and driven plates 94 and 1%, respectively. At least two guide elements 116 are selectively and detachablysecured to the bars 1% of the frame 104 for accommodating therebetween the end edges of the web 74 as the latter is wound about the core 76. The guide elements embody collars secured by set screws to the one bar 106 which is the last bar over which the web 74 travels as it is wound upon the core 74}, this being shown most clearly in Figure 4.

In Figures 10 to 13, inclusive, there is shown a modified form of the present invention which employs means for selectively varying the degree of limited reciprocatory movement in both directions of the sleeve In this embodiment of the invention, the worm gear 162 and the gear 42 and a cam member 35 attached thereto are eliminated and are replaced with a gear train having a first gear 112 mounted upon the shaft 26 and meshing with a second gear 114 rotatably carried on one face of a plate 116. A reverse gear 11% is also mounted upon the plate 116 and is in mesh with the gear 114. A feed shaft 12% is journaled in the upper ends of the legs 2% and 30 of the support member carries adjacent one end the last gear 122 in the gear train and'alternatively in meshing engagement with the gear 114 or the reverse gear 118, as shown in Figures 12 and 13. The plate 116 is mounted upon the leg 28 for rocking movement about a horizontal axis and the rocking movement is accomplished by the'downward pull of the'solenoid core 124 when the solenoid coil 126 is energized. A spring 123- has one end anchored on the leg 28 and its other end operatively connected to the plate 116 and'biases the plate 116 to the position in which the gear 118 is out of meshing engagement with the gear 122 and the gear 114 is in meshing engagement with the gear 122.

The shaft 121} is provided with screw threads as at 130 and a carriage 132 is mounted upon the shaft 120 for movement along the threads 130 in response to rotational movement of the shaft 12%. The carriage 132 is connected by an arm 56', Figure 10, to a bearing assembly 69 carried by the sleeve 34. The carriage 132 moves from the full line position to the dotted line position and return in Figure 10.

A rod 134 is slidably mounted between Urunnions 1% carried by the upper ends of the legs 23 and 3t) and carries thereon a pair of switch actuating stops 138 and 1 arranged in spaced relation therealong. The carriage 132 moves between positions in which it engages alternatingly the stops 138 and 141 to effect the sliding movement of the rod 134 and to cause the stops 142 on the rod 134 to operate the switch am 144- between on positions and off positions.

With the shaft12ti rotating in one direction, the carriage 132 will be carried along the threads 1311 to a point Where it abuts the stop 141i, shifting the stop to the dotted line position in Figure 10 and actuating the switch arm 144 to an on position. This closes the contacts within the switch 146 and results in the energizing of the solenoid coil 126 to draw the core 124 downwardly and to effect the shifting of the plate 116 to the position in which the reverse gear 118 i s in mesh with the gear 122, thus resulting in the reversing of the direction of rotation of the shaft 120 and carrying the carriage 132 back to abutment with the stop 133 which effects the shifting of the switch arm 144- to the off position. The spring 128 then returns the plate 116 to the position in which the gear 122 is driven in the forward or clockwise direction by the meshing engagement of the gear 114 therewith.

A pair of feed rollers 143 and 150 are positioned in cooperative relation with respect to the tensioning frame 104- for feeding the web 74 from a web source to the tensioning frame 104 under tension. The feed rollers 14% and 150 are shown in Figures 14- to 16 and include a standard 152 rising from the base 20 and rotatably supporting the feed roller 14?) by means of a horizontally disposed shaft 154 carrying the roller 148 on one end and having coupling means 156 on the other end for attachment to the drive shaft of a variable speed motor, the latter not being shown as not being a part of the invention. The other feed roller 156 is mounted upon a stub shaft 158 which projects from an arm 160 carried on the upper end of the standard 152 for swinging movement about a horizontally axis. Adjustable spring means as at 162 biases the arm 160 to a position in which the feed roller 159 is in rolling engagement with the driven feed roller 148. A lever 164 carrying a cam member 166 on its one end thereof is pivotally connected in the arm 160 and is operable to lift the one feed roller 150 out of rolling engagement with the other feed roller 143.

In Figures 2 and 9 it will be seen that a semicircular pan 168 is supported upon the one leg 28 and receives therein the lower portions of the peripheries of the drive plate 94 and the driven plate 100. A quantity of oil or other lubricating material is kept within the pan 168 and serves to lubricate the leather face 98 and to provide a slipping clutch engagement of the plates 94 and 106 and to thus prevent the tearing of the web 74 as it is being wound upon the core 70 if for any reason the web 74 were stopped in its movement from the source of supply, such as a sewing machine or other production machine.

The web wind-up machine of the present invention, in each of the embodiments shown, Will be found to be useful in any establishment in which it is desired to wind up or roll up a web of cloth or other fabric which has one edge thicker at one end of the roll than the edge at the other end of the roll. This may be due to sewing of a hem along the one edge and subsequent doubling of the material. The roll formed by the machine of the present invention will be found to be stable for the reason that the reciprocatory movement of the sleeve upon the shaft causes the web to shift relative to the guides and to effect the overlaying of the end edges of the web and to eliminate the building up of the roll on one end to a thickness greater than the other end of the roll.

The embodiment of the invention shown in Figures 10 to 15, inclusive, enables the operator thereof to quickly adjust the positions of the stops 138 and 140 and to effect thereby the varying of the degree of limited reciprocatory movement of the sleeve 34 upon the shaft 26.

While only preferred embodiments of the present invention have been shown and described herein, other embodiments are contemplated and numerous changes and modifications may be made in the invention within the scope of the appended claims.
