COLLINS, OF CUYAHOGA FALLS, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, '10 MILLER RUBBER COMPANY INC., 013 WILMINGTON, DELAWARE, 'A CORPORATION on DELAWARE WINDING MACHINE Original application filed December 14, 1926, Serial No. 154,748. Patent No. 1,687,607, dated October 16,

1928. Divided and this application filed April 27, 1928.

My said invention relates to winding means of the type used in slitting and rewinding machines and the present application is a division of an application filed by me in the United States Patent Office on the 14th day of December, 1926, Serial Number 154,748 which has matured into a Patent No. 1,687 607 Oct. 16, 1928.

One of the objects of the invention is to provide means by which the plural bands may be wound in such a manner as to avoid stretching the material unduly, and to roll it in such form that it will remain smooth and free from wrinkles.

Another object is to provide means to enable the ribbon spools to be readily and collectively removed when sufficient quantities of ribbon have been wound thereon.

A'further object isto provide simple and effective means for severing the rewound portions of the ribbons from the unwound portions and to enable the ready attachment of such unwound portions to fresh spools and their convenient replacement in winding position.

With these and other objects in view the invention comprises the novel features of construction and arrangement and combination of parts hereinafter described and as set forth in the appended claims defining the 1nvention.

What I at present consider the preferred embodiment of the invention is illustrated in the accompanyingdrawings in which:

Fig. 1 is a central vertical longitudinal section of a sufficient portion of the machine shown in my aforesaid application to afford an understanding of the invention.

Fig. 2 is a plan view thereof.

Figs 3 and l are respectively a plan and edge view of the guide strip 28.

Fig. 5is a detailed elevation, partly in section, of the spool guide.

Fig. 6' is an end view of the bar 31.

Fig. 7 is a transverse vertical section of the bar and spool guide element.

Figs. 8 and 9 are respectively a plan vlew and edge view of plate 35.

Figs. 10 and 11 are similar views of plate Referring by reference characters to this Serial No. 273,293.

drawing the numeral 27 designates an idle roll around which the ribbons pass after hav ing been formed by the slitting mechanism disclosed in my aforesaid application, and from which roll they are led to guides which accurately align them with the rewinding rolls. These guides are formed by a steel plate 28 Figs; 3 and 4: having two sets of smooth polished slots 28 milled in its 0pposite faces, one set being one-half inch in width, and the other three-fourths inch and correspondingly placed.

, The plate is removable and reversibly held so that it may be readily inverted to effect the change of width of guide. Small guide plates 28 are secured to the fences between the slots so as to provide nearly closed guides for the ribbons.

This guide plate is located in close proximity to the winding mechanism, whch will now be described.

This comprises a pair of rolls 29 and 30 which are driven at a slightly greater surface speed than the platen. roll 2 of the slitting mechanism, conveniently by a train of gearing from the platen roll shaft. .The rolls 29 and 30 are provided with knurled or roughened surfaces to exert a pulling or turning efiect on the ribbon rolls which are floatingly supported by the rolls 29 and 30. In order to properly position the ribbon rolls, I provide a ribbon roll bar or block 31 removably carried by the frame members and which in turn carries a plurality of upstanding ribbon roll spacing plates or bars 32, Figs. 5 to 7.

Each of these spacers is provided with narrow substantially L-shaped grooves 32*, and the upper part of each spacer is slotted entirely through in alignment with the groove or grooves. The ribbon rolls 33 are of a width to pass between the spacers and are provided with small axial projections at each end to engage the L-shaped slots in the spacers.

When the ribbon rolls are empty, and resting upon the pulling or winding rolls 29 and 30, these projections will be in line with the lateral extensions of the L-shaped slots, which extensions are inclined upwardly as shown at 32". This enables the fresh empty ribbon will be raised until its axial projection is out of line with the branch slot and will consequently be held against accidental removal. As the winding continues, the spools or rolls will rise till their central eyes align with the through slots in the spacers at which time (the spools being full) a skewer may be passed through the spool eyes and all lifted out together.

In order to enable the ribbons on the filled spools to be easily separated from the stock in the machine, and such stock readily attached to fresh spools, I provide the following means.

Adjacent the roll 29 I provide two juxtaposed plates'34 and 35 (Figs. 1 and 2 and 8 to 11). Plate 34 has slots 34 across its face corresponding in width to the width of ribbons.

It is also rebated along its edge, as indicated at 34 to provide a guide for a cutting knife. Assuming that the spools have had the requisite amount of ribbons Wound there- 'on and been lifted out by the skewer, they are then placed on plate 34 and rolled along the same to lay the ribbons in the slots 34*, f

after which the skewer is supported in the forked or slotted upper ends of brackets 36. The operator may now readily sever all the ribbons by passing a suitable cutting knife along the rebated edge or guide 34". The rolls of ribbons on the skewer may now be removed and it will be found that the ends of the ribbon lying on plate 34 will be of the proper length to pass around a new set of ribbon rolls in re-winding.

For this purpose I provide the plate 35 above referred to, which is of identical construction to plate 34, except that the slots 35 are of the proper width to receive the spools or rolls 33 (usually of steel). One of these rolls being dropped into each slot with the spool contacting with roll 29, the free end of each ribbon will be of such length that it may be lifted up from plate 34 and carried over the top of the corresponding spool and tucked into starting position, and each spool may be rolled up over roll 29 and dropped into the space between the spacer plates in winding position.

Plates 34 and 35 are made removable and replaceable for different Widths of ribbon.

Having thus described my invention what I claim is: I

1. In a winding machine of the type employing a pair of spaced driven winding rolls, re-Winding spools adapted to be supported by and driven through frictional contactof said rolls and the stock wound on said spools, ribbon guiding means comprising a plate having elongated ribbon channels in its surface, said channels being located in a plane substantially coincident with the tops of the re winding rolls.

2. In a winding machine of the type employing a pair of spaced driven winding rolls and winding spools adapted to be supported by and driven through frictional contact of said rolls and the stock wound on said spools, said spools having axial projections, guide means for said spools comprising uprights located midway of said re-winding rolls and having vertical slots in their juxtaposed faces to receive said spool projections, and having angular entrance slots adjacent the periphery of one of the re-winding rolls. 7

3. In a winding machine of the type employing a pair of spaced driven re-winding rolls and winding spools adapted to be supported by and driven through frictional contact of said rolls and the stock wound on said spools, said spools having axial hub proj ections and axial passages therethrough, guide means for said spools comprising uprights having vertical slots in their juxtaposed faces to receive said hubprojections, said axial'passages being adapted to permit the passage of a skewer through all of said spools when alined with said through slots for simultaneous removal of all the spools.

4. In a winding machine of the type employing driven re-winding rolls and floating spools supported thereby, a plate member adjacent said re-winding means having ribbon receiving channels, and a knife guide arranged transversely of said channels.

5. In a winding machine of the type employing a pair of spaced driven winding rolls and winding spools adapted to be supported by and driven through frictional contact of said rolls and the stock wound on said spools, said spools having axial projections, and guide means for said spools comprising uprights located midway of said re-winding rolls and having vertical slots in their juxtaposed faces to receive said spool projections, and having angular entranceslots adjacent the periphery of one of the winding rolls, and a ribbon support adjacent said one of the winding rolls, said support having ribbon receiving channels intersected by a transverse cutter guide, the portions of the channels adacent said winding roll being widened out sufliciently to receive the spools, whereby the latter may be placed in the channels for ribbon attachment and then rolled over the face of the winding roll for entering the hubs in the guides.

6. In a winding machine of the type employing driven re-winding rolls and floating spools supported thereby, a plate member adjacent said rewinding means having ribbon receiving channels, and a knife guide arranged transversely of said channels, and means adjacent said plate for supporting the filled spools with the ribbons resting in said channels.

In testimony whereof, I aifix my signature.

ARTHUR E. COLLINS.
