I 7 Claims.

This invention relates, to winding or reeling mechanism and more particularly to mechanism for reeling long strips of blanks for various articles such as containers, container covers and the like.

One of the principal objects of the invention is to provide an improved reel for such mechanism and another object is to provide a novel and convenient tension controller or loop controller for this type of apparatus. Another object is to provide such a loop controllerwhich is adapted to maintain the rear part of the winding stripmaterial in a comparatively slackened condition and to maintain the forwardportion or that 5 between the loop controller and thereel in a more taut condition. I

This application is a divisional application 0 subject matter divided from my co-pending application, Ser. No. 668,571,- filed April 29, 1933, o Machines for making material for containers, container covers and the like, now Patent No. 2,083,566, of June 15, 1937, to which reference may be had.

The means I prefer to employ for accomplishing the above objects together with other advantageous features of my invention are illustrated in the drawing accompanying and forming part of this specification and in which- Figure l is a diagrammatic side elevation of my improved reeling mechanism showing parts in section.

Fig. 2 is a diagrammatic plan of the same also showing parts in section, and

Fig. 3 is a detail side elevation of one of the reel collars.

Referring to the drawing, the letter D refers generally to the reeling or winding mechanism and B refers to any suitable mechanism used in conjunction with the reeling mechanism, such as a stamping, embossing or other mechanism.

The reeling or winding mechanism is preferably furnished with longitudinal frame members such as In and II, the latter being preferably secured to the member Ill by suitable bolts and the member Ill being supported by suitable means connected with the floor such as the strut I 2. In this instance-the member ID is secured to the forward end of the frame 2 of the mechanism B.

Carried by the right hand portion of the mem- 50 her H is the reel l4 which includes two comparatively large disks [5 and I6,.the disk [5 being integral with a cylindrical portion or drum ll having a hub l8 by which it is mounted on the shaft 19, the said shaft I! being rotatable in the bearing 28 of the frame member H and having suitably secured to it a grooved wheel or pulley 2| by which it is rotated. The wheel 2| is turned by the belt 22 which itself is driven by the grooved wheel 23 secured to the shaft 5 which is journaled on the frame 2.

There is a shaft 21 having feed rollers 24 secured to it and also a gear 26 meshing with a gear .25 secured to the shaft 5., The shaft '5 has a feed drum or roller 28 fastened to it and is turned by suitable power means (not shown) connected with the stamping or other mechanism B used in connection with the reeling mechanism and said means are suitably timed to act with said mechanism B.

The hub I8 of the reel I4 is externally screw threaded and mounted on itis a hand nut 30 which normally holds the flanged member 3! against the disk IS, the said flanged member having a recess 32 in which the hand nut lies. The shaft i9 is reduced in diameter and screw threaded at 33 and on it is anut 34 which is effective for adjusting the spring 35 coiled around the portion 33. The spring 35 bears against a collar 36 which is slotted at 36a to engage a pin 33a secured in the portion 33 of said shaft iii. The collar 36 bears against the free collar 4| which in turn bears against the hub 18.

There is a drum or wheel 38 secured to a shaft 39 rotatable in a bearing 40 mounted on the frame member ll. secured to its rearward part and said sprocket is driven by a chain 43 driven by the sprocket 44 on the shaft 5.

On the frame member 10 is secured a bracket 45 which supports the guide member or chute 46 for supporting and guiding the web or strip of material S, which is permitted to pass downwardly at SI and then to be drawn upward through the fiat tube 41 which is mounted by means of its. ears 48 on a rod 49 secured transversely on the frame member II.

The upper part of the flat tube 41 has a resilient device 50 in the form of a slightly bent thin plate or spring leaf or extension and which element normally bears lightly on the drum or wheel 38 and when the strip S is drawn around the drum 38 on rotation of the same, the plate against the disk l5 so that the reel proper consisting of the plates I5 and I6 and drum I1 is frictionally held between the flanged member 3| and the face plate 5! and consequently the shaft The shaft 39 has a sprocket 42 loop SI and then up into the tube 41.

I9 can turn at a slightly greater speed than the reel proper. This being the case the difference in rates will increase as the strip S is reeled and piles up between the disks I5 and I6. Thus it is practicable to reel up any amount of web the reel is capable of holding, with one speed of the wheel 2|.

The rod 49 acts as a pivoting means for the tube 41 and spring plate 50 which members will act as one if oscillated on the rod 49 and thus the plate 50 can be made to bear more or less on the blank strip S. The tightness of the fit of the parts will usually be sufficient to hold the plate and tube in any desired position with relation to the wheel 38.

The shaft 5 operates at a constant speed and the shaft I9 operates at a constant speed but more slowly than the shaft 5 due to the larger diameter of the pulley 2I. Also the shaft 39 operates at a constant speed but more slowly than the shaft 5 due to the sprocket 42 being of larger diameter than the sprocket 44. The drum 3B is of larger diameter than the sprocket 42 but its surface speed is slightly less than that of the drum I! when the latter is driven atits slowest speed. Consequently the part of the strip at $2 is always in a taut condition.

The operation of the reeling mechanism is as follows:

The strip of blanks S is fed through the feed drum 28 and rollers 24 to the stamping or other mechanism B. From the mechanism B the strip S passes through the chute 46 and then passes downwardly over the curved portion 46a into a Then upward through said tube under the plate 50, around the wheel or drum 38 to the reel I4.

The peripheral speed of the reel I4, if there were no slippage in the friction drive thereof, would be slightly greater at least than the peripheral speed of the feed rollers 24 and. cooperating drum 28. causes a drag on the strip S, so that the strip S is maintained taut between the reel I4 and drum 38, but given a certain amount of slackness between the drum 38 and feed rollers 24 resulting in the loop SI which tends to increase or decrease according as the pressure of the plate 50 permits. Slightly oscillating the tube 41 and plate 50 causes the latter to bear more or less on the strip S, so that the size of the loop SI can be made to vary. Ordinarily the mere closeness of the fit of the ears 48 on the rod will be sufficlent to hold the tube 41 in such position that the plate 50 can be given the desired pressure on the strip S, but if desired the ears 48 can be made with suitable clamping means so that the tube 41 can be positively clamped in position.
