Abstract: 1,054,565. Winding and reeling. K. P. LEE. July 15, 1964 [July 29, 1963], No. 29153/64. Heading B3E. [Also in Divisions B4, B5, B6, B8 and D1] Apparatus for rolling a web of pliable material Y comprises material forcing means F to receive and move the material Y therethrough, means 26 to feed the material Y to the forcing means F, and a roll-up mechanism 65, comprising a plurality of interconnected conveyers with the last and penultimate conveyers fixed at an obtuse angle relative to each other, to receive the material Y from the forcing means F and to curl the material Y back upon itself and into a roll R. The apparatus may be used for rolling carpeting, as shown, textile fabrics, linoleum, wallpaper or metal sheets, e.g. aluminium, galvanized iron and/or stainless steel. The material feeding means 26 consists of a feed table comprising endless belts 63 passing around pulleys 61, 62, the pulleys 61 being mounted on a shaft 60 driven from a motor M by the system of shafts, belts and pulleys shown in Fig. 2. Spiked clips 105, Figs. 12 and 13 (both not shown), may be provided on the belts 63 to grip the carpeting. The forcing means F comprises presser rolls 35 mounted on a freely rotatable shaft 36 and feed belts 38<SP>1</SP> passing around pulleys 40<SP>1</SP>, 42<SP>1</SP> on shafts 41, 43 driven by the motor M through the system shown in Fig. 2. The shaft 36 is spring- loaded so that the rolls 35 engage the material Y on the belts 38<SP>1</SP> and are driven thereby. The roll-up mechanism 65 comprises segments 66, 67, 68, 69 having side walls 66<SP>1</SP>, 67<SP>1</SP>, 681, 691 with shafts 72, 79, 82, 88, 89 journalled therebetween and the walls 68<SP>1</SP>, 69<SP>1</SP> being fixed relative to one another to provide a troughlike zone at the end of the mechanism 65. Belts 76<SP>1</SP>, 91<SP>1</SP>, 94<SP>1</SP>, 100<SP>1</SP> to support the material Y are trained around pulleys on the shafts 72, 79, 82, 88. 89 and are driven in unison with the belts 38<SP>1</SP> from the motor M through a belt and pulley system. Means 106, Fig. 2, is provided to curl the segments 66, 67, 68, 69 into material-receiving condition. With the mechanism 65 empty, a motor 107 is energized to drive gears 111 through slip clutches 112 to force rack bars 115 rearwardly and upwardly to move the segments 66, 67, 68, 69 from the position of Fig. 2 to that of Figs. 4 and 8 through links 116, 117 pivoted to the shafts 79, 88, respectively. Each rack bar 115 is held in engagement with the adjacentgear 111 by a stirrup 113 having rolls 114 thereon. The swinging movement of the segments 66, 67, 68, 69 is limited by means L comprising loop straps 121, 122, 123, Figs. 8 and 9 (the latter not shown), and pins 124, 125, 126, 127, 128 having headed ends H. Material deflectors 70, Figs. 8 and 15, are normally held retracted but are moved into position on the moving of the segment- 69 into the curled-up position. Each deflector 70 comprises a steel strap 130 provided with a loop 131 extending around the shaft 88. A curved lip 134 on each strap 130 deflects the leading edge e of the material Y into a coil, a smooth surface on the strap 130 being provided by a nylon facing 135. Normally a hook 142 on a trip lever 139 engages a hook 143 mounted on one end of the armature core 147 of a solenoid 144. Upon energization of the solenoid 144, the core 147 is pulled upwardly to pull the strap 130 downwardly so that it swings out against the action of a spring 141. Fig. 16 (not shown), and away from the end of the lever 139 to dispose the curved lip 134 in operative position, Fig. 15. When the solenoid 144 is de-energized the spring 141 retracts the deflector 70 out of the operative position. As the roll R becomes larger the segments 66, 67, 68, 69 open up so as eventually to rest on supports 66<SP>11</SP>, 67<SP>11</SP>, Fig. 8, in the position shown in Fig. 2. A pole or shaft may be inserted through the core of the roll R after rolling. Before the roll R is removed the material Y is cut by a unit 30 which comprises a doubleedge knife 150. Figs. 3 and 15, for carpeting and fabrics or a double-edged saw for metals. The knife 150 is mounted on a dolly 153 riding on a track 154 directly beneath a slot 151 in a bridge portion 152 between the feed table 26 and the forcing means F. The dolly 153 is secured to an endless chain 155 trained around sprockets 156, 157, 158, 159, the latter sprocket being drivable in either direction by a motor 160 to move the knife 150 transversely of the material Y when it is stationary. Limit switches 161, 161<SP>1</SP> are provided at each end of the path of the dolly 153 to stop the motor 160. The dolly 153 contains means to cause the knife 150 to vibrate, i.e. reciprocate vertically. After the desired amount of material Y has been measured by a meter 162, Fig. 1, the attendant grasps a handle 183 on a lever 184 at each side of the machine to pull the lever clockwise, Fig. 15. Movement of the lever 184 causes arms 168 to lower a press bar 170 and springs 172<SP>1</SP> urge the serrated bottom edges of a channel 171 into contact with the material Y to straddle the slit 151 and hold the material firmly during cutting. After cutting, the lever 184 is swung upwardly to raise the bar 170 and the curved ends 176 of deflectors 175 are lowered by handles 163 on levers 164 so that the leading edge of oncoming material is deflected towards the lower quadrant of the rolls 35.
