Blessing, Oakland, Calif., assignor to Blessing Packagingv Company, a corporation oi California I? Application March-l9, 1948; Serial No. I5,869 v Claims. (o1. 242-58) This invention-relates to garment bas i's o the kind described in my copending application SerialNo, 654,400, filed Mar. 14,1916, now abandoned. More particularly this invention relates to' various improvements in this type of machine as will appear hereinafter. 1 n

' One of theobjects of this invention is to improve the tubular paper feed in theseymachlnes'. Another object is to facilitate the loading of the machine with rolls of tubular paper. Other ob.- iects than those specifically mentioned will appear .from a consideration of the following specification and accompanying drawings, in which: p H Fig. 1.1's an elevation of my machine, showin certain details;

vFig. 2 is a frontal feeding mechanism;

Referring now to Fig. 1, the apparatus cornprises a framework or first frame ilk-into which there. is fitted a roll i2 of tubular paper the web 14- of which is threaded over a roller 16 thence through a cutting, folding, and stapling appa ratus-at l8 and thence to the left in Fig. 1 and downwardly in the direction 20 to envelop a garment (not shown) partially, suspended by a coathanger .22 supported on upright post 24.; Post 24 is readily removable so that the machine maybe loaded as illustrated in Fig. 1. -The rolls of tubular paper are quite heavy. In order to facilitate loading the rollsinto the machine, the apparatus comprises a rollsupport frame or rack 26 having a pair of oppositeside members pivoted at one end on bracket 28. see liedOrr-floor 3t of the machine. Rack 26 comprises arrns 26a and 261) provided with horizontally alignedpivotalsupports 26c and 26d. The upper ends of arms 25a andjZfib are .pro- "vided with horizontally aligned facing pins 26c and 26jwhich receive a transversej ;member such as tube 26g with a close fit. The'gtubular paper of roll I2 is secured onto roll support means adapters 2671. and Zfik which in turn receive the pivoting supports 26c and 26d respectively. In the modification shown, the adapter 26h is not rotatable about the axis of the roll l2, with respect to the roll; both must rotate together for rea'sonspresently to be pointed out. Inorder to load the machine tubular paper, the roll is placed in position l2 on the floor in front of the machine opposite the area between arms 26a and 26b." Rack 26 is now pivoted to the dotted line position. Inthis position the arms 26a and 262) are free to diverge sufficiently to allow pins 260 and 2801 to elevation of the loading and register with and enter the bearing holes in and 26h. The tube 269 is now used as a handle tograise the roll to the full line posit on. Before completing the movement, the web 14 may be threaded under a feed controlling1'o1ler'32} which will presently be more particularly described, and held while rack 26*is forced to its full line position against stops 34 mounted on the walls of frame 10. Stops Gtform partsof cams 35 which diverge forwardlyj As the arms move inward (to the right) they are positively forced together so as to insure full entry of pins 25c and'ZSd, and to fix'the roll horizontally.

' A web brake 38 is provided on top of the ma chine'at the cutting region which engages'the web so that after it is outthe portion below roll l6 will not fall back into themachine. This is a simple friction brake which allows forward movement of the paper when pulled toward the operator (leftward in Fig. 1). 1

Much improvement in web cutting is effected by lreepingthe web is fairly jfiat during cutting. To do this with tubular paper from rolls presents typical difficulty for such rolls because the web varies slightly in thickness transversely and longitudinally in an unpredictable manner.

The roller 32 is provided to rest on the web id and maintain tension thereon. To maintain a uniform pull across the web, the roll 32 is mounted in loose bearings 32a in arms 3% which arms are pivotedat 32c on rack 25. This looseness of. bearings permits thei'oller 32 to pull uniformly on'the vertical part I la-0f web M.

v In order to maintain tension in web Ma, the roll I2 is prevented from overrunning due to 'ac quired momentum and the weight. of roll 32. A

hand are of leatherzbelting secured tonne-arm 321) as at 32d and passed over the adapter 26h and downwardly to ananchor 32c on arm 26a.

A groove 32f is provided in adapter 26h for this As the tube 32 drops down it pulls purpose. 32c tangent to the groove and stops rotation of the roll of tubing I2. However, when the operator pulls on the web as at 20, the tube 32 raises to release the band 320 and allow the roll l2 to turn as rapidly as desired. It stops instantly 2,545,337 I p v at one end on said opposite side members for movement on said first frame, a transverse member slidably engaged with the other end of each side member, each side member being flexible to enable such member to be moved away from the other side member, and roll support means carried on each side member to support a roll of sheet material for rotation between said side members.
