Abstract: 397,784. Packages. ARMSTRONG CORK CO., Lancaster, Pennsylvania, U.S.A. -(Assignees of Hawker, C. F.; Herr, B. F. ; and Rottmund, F. G.) March 9, 1933, Nos. 7184 and 7185. Convention date, March 16, 1932. [Class 94 (i).] Relates to the enclosure of linoleum rugs or like coverings to form a cylindrical package. The rugs are stocked on an inspection table 2, Fig. 1, and are passed singly through rolls 3, for printing on the bottom surface, on to a belt conveyer 4. The conveyer 4 forwards the rug to rolls 7, 8 for feeding into a conditioning chamber 9 in which it is heated to approximately 100‹ F. to facilitate rolling. The rug is moved through the chamber by a steel or slat conveyer and arrives at the rolling device 10 comprising an idle roll 12 and driven rolls 13, 14. A thin wooden core is placed between the rolls, the end of the rug being secured by means of a fabric apron; on rotation of the rolls 13, 14 in a counterclockwise direction the rug is formed into a roll. At position 15 a single paper tube, or two paper tubes 55, Fig. 1A, are placed round the roll by passing over the ends towards the centre. Wooden end-pieces 56, Fig. 1B, are placed in the ends of the tubes, the assembly is centred at position 16 and the ends crimped by devices 17. At the position at which the paper tubes are placed over the roll, the roll passes from the grip of belts 18, 19, Fig. 2, passing round flanged pulleys 30, 36 beneath springs 51, one of which is shown. The end is turned up at 54, and the supports 34 are bevelled to facilitate the application of the tubes. The assembly is rolled on the supports 34 to the centring device, Figs. 6 and 8, the roll now rests on rollers 127 between centring heads, of which one is show in Fig. 6. The head is mounted on a slid 105 horizontally reciprocated by a shaft 100, terminating in a piston head 98 in a piston cylinder in a link 96 actuated by an eccentric 95. A compression spring 101 connects the parts and ensures a resilient action. The slide 105 carries a member 107 with a housing 108 in which the head is rotatably and resiliently mounted. In action, the head passes into the tube until the flange 110 abuts against the edges, an extension plate causing the roll to be centrally disposed within the tube. The tube may be rotated to permit application of adhesive strips 55A, Fig. 1A, to join the sections together. The eccentric is automatically clutched and declutched to give time for the various operations. The roll is moved into position from notches 118, Fig. 8, in which it rests on arrival from the plates 34, by T-shaped arms 119, which rise and cause it to fall into notches 126, where it rests on the rollers 127 for the centring operation. Upon the next ascent of the arms 119 the roll is lifted land caused to a similar pair of receiving notches in the end-crimping machine, Fig. 13. It is now in position on bearings between crimping heads 128. The heads are mounted on sliding bases reciprocated in the same manner as the heads 109. Each head is formed with a groove 134, Fig. 13, to engage with the projecting ends of the paper tube. Pins 135 grooved at 137 are mounted in recesses 136 and secured by screws 139 so that one edge projects into the groove to turn the paper over into the position shown in Fig. 1B. The ends of the tube may be oiled to facilitate crimping, which may be continued until grooves 55c are formed. During the process a resiliently mounted clamp descends to prevent the roll from rotating.
