MAGEINE FOR MAKING SURGICAL BANDAGES.
APPLICATION FlLBD 513F128, 191.2)
1,109,184. Patented Sept. 1, 1914 2 EHEETS SHEHT 2v g 2? 5 2 g g I z l W spaced apart on the shaft a distance equal to the width of thehandages to be made. of the wheels 24 is provided with a series of radially disposed-slots 25 in which are mounted the warp separators 26, one of which is shown on an enlarged scale in Fig. 6, from which it will be observed that the outer end of the separator is tapered as indicated at 2'? to facilitate its rojection between the warp threads of the abric. These separators arealso provided with a lateral projection 28 adaptedto engage in acam slot 29 formed in the cam 31 fixedly mount ed on the stationary shaft 21 adjacent the wheel 24. It will be observed that the cam slot 29 isprovided with a high portion at its upper side which will pro ect the separators in succession beyond e periphery of the rotating wheels 24 as they travel around the cam. The projection of the separators through the fabric 13 will displace the warp threads in both directions from the tapered ends 27 of the separators so as to compress or compact the warp threads on each side of the separators, leaving a warpless space between the compacted portions. For the purpose of holding the fabric in coiiperative. relation with the separators to insure the projection of the separators through the plane of the fabric, I have mounted upon the shaft 23 "a lpluralit of wheels 32 directly over an in a inement with the wheels 24. Each wheel 32 is provided with a series of slots or recesses 33 adapted to receive the ends of the separators projected from its companion wheel 24. The fabric is accordingly held down by the wheels 33 against the peripheries of the wheels 24so that the separators will be forced through the fabric between the warp threads as the fabric is fed along.
Between the separating devices and the winding spindle 15 I have mounted a roller or platen 3i and above the platen and adapted to cooperate therewith I have mounted a plurality of disks 35, these disks being spaced to correspond to the spacing of the separating devices and being disposed in alinement with the points of the separators. The disks may be held in cooperative rela' tion with the roller platen by any suitable mechanism. In the present instance, however, I have shown each disk as carried by an arm 36 pivoted on a transverse rod 37,
the rear end of each arm. heing adapted to overlie a leaf spring 38 secured to the frame of the machine. In order to regulate the pressure of the disk against the platen. l have equipped each arm with an adjusting screw 39 adapted to contact with the spring 38 and by means of which in;
pressure of the disk may be increased or diminished', as desired.
The disks 35 may be d the 11- "sure upon the disks may be so regulated that the weft threads extending across the warpless spaces formed by the separators may be entirely severed as they pass between the disks and the platen. In this event the bandages will be separated one from the other and will be-wound up on the winding spindle 15 as distinct and-sepa-' rate bandages. Preferably, however, the disks 35 are rather dull and the pressure is so regulated that the weft threads will besimply'crushed and weakened by the disks so that the roll of connected bandages wound up on the windin spindle ma be readil broken off along e weakened ines of we thfleads to provide the individual bandage ro It will be manifest that by means of my improved machine above described I am enabled to produce a number of complete bands 3 during one passage of the fabric throng the machine and, that the completed bandages will each have a velvety edge formed by the projecting weft ends and that the tensile strength of thebandages will be increased at the edges by the compacted weft threads so that the bandages will not become torn or distorted wllrn tightly applied to a wound.
In the above description I have referred th the longitudinal threads as warp threads and transverse threads as weft threads, but it will be obvious that the machine is equally adapted for spacing and compacting'weft threads and weakening or severing the warp threads if it should he found desirable to run the fabric throu h the machine in a transverse direction. he terms warp and weft threads are, therefore,.merel relative and I do not wish to be understoo as limiting the action of the separating devices to the warp threads, nor the weakening and separating devices to the weft threads.
It is believed that my invention and its mode of operation will be sufficiently understood from the foregoing without further. descri tion and it will be obvious to those skillerlin the art that various modifications in the structural details disclosed ma made without departing from the see of the invention.
