3921. Fell, J. C., [Cottrell & Sons Co., C. B.]. Feb. 23. Folding paper; cutting, associating, and delivery apparatus.-Relates to apparatus for cutting, associating, folding, and delivering products from printed webs of paper. Fig. 2 shows a vertical section of the apparatus, and Figs. 23 and 24 are diagrammatic views showing the parts in different positions. The web or associated webs of paper A is led from the printing- apparatus to a pair of cutting - cylinders 116, 117, and thence to the folding &c. cylinders 1, 29. The cylinder 1 is twice the diameter of the cylinder 29, and, in the e arrangement shown, is provided with folding jaws or grippers 11, 12 in the recess 4, and with a pasting-blade 81 in the opposite recess 4<a>. The cylinder 29 has a folding-blade 36 co-operating with the jaws 11, 12, and a set of grippers 57 for taking the leading end of the web. The folding-mechanism operates in a similar manner to that described in Specification No. 11,965, A.D. 1899. The grippers 12 of the folding-jaws consist of a set of fingers independently adjustable on a shaft 10 journalled in arms 8 pivoted, one at each end of the recess 4, on plates 5 screwed to the ends of the cylinder. The axis on which the arms 8 are pivoted coincides with the peripheral line of the cylinder 1, and, having this axis as a centre, carved slots 6 are formed in the plates 5, through which the ends of the gripper shaft 10 project. The gripper bar 11 is fixed to or formed with the arms 8. The gripper jaws 11, 12 swing together about the axis of the arms 8, whereby the jaws are moved into the radial position for folding, as seen in Fig. 2, and then into the position seen in Fig. 23 for delivering the sheet, fold first, tangentially of the cylinder into the tapes 102, 103. The arms 8 are operated by a stationary grooved cam 16 engaging an arm 15 fixed to one of the trunnions of the arms. The shaft 10 is operated to close the grippers 12 on to the jaw 11 by an adjustable spring rod arrangement connected to an arm 20 on the shaft 10, and to open them to take the fold and to deliver the sheet by cams fixed to the framing. The outer edge of the folding-blade 36 always projects beyond the periphery of the cylinder 29, and this blade is fixed to a split bar 35 carried by arms 42 pivoted on plates 32 fixed to the ends of the cylinder 29. The axis of the pivots of the arms 42 preferably coincides with the peripheral line of the cylinder 29, and the arms are rocked to cause the blade 36 to swing with the jaws 11, 12 during the formation of the fold. The pasting-blade 81 slides radially in the recess 4<a>, and is projected from the cylinder to take a supply of paste from the paste roller 98, by arms 78 on a shaft 76 rocked, against the tension of a spring rod arrangement, by a fixed cam on the framing. The paste roller 98 is on a reservoir 99 having screws 100 for adjusting the supply of paste. When two sheets are being associated and folded together, the leading edge of the first sheet is taken by the gripers 57, is pasted along the fold line by the blade 36 pressing it against the pasting-blade 81, Fig. 24, and is retained by the grippers until the second sheet is associated with it and until the fold is completed. The second sheet passes down between the cylinders, and its leading edge is stripped from the cylinder 1 by a rotary stripper 110. When the two sheets are folded together into the folding-jaws, the second is cut off by the cylinders 116, 117, and the first is released by the grippers 57, so that the sheets are carried on by the folding-jaws and delivered to the tapes as shown in Fig. 23. Inclined recesses 105 in the cylinder 1 come opposite the grippers 57, and these recesses admit air under the leading edge of a sheet and remove it, or assist in removing it, from the cylinder 1. The cylinder 29 is provided with a recess or cut-away part 71, between the grippers and the folding-blade, to permit parts of the sheet to enter and so yield, while held by the grippers, to the pull of the blade 36 when pasting the sheet and when tucking the fold into the jaws 11, 12. A bed-piece 74, adjustable by screws, mav be placed in the recess 71 to limit the yield of the sheet. The tapes 102 run in grooves in the cylinder 1, and the folding- jaws are recessed for their passage. The stripper 110 consists of fingers on a bar 106 carried by arms on a shaft 112 driven in the direction shown by the arrow. The fingers 110 enter grooves in the cylinder 1, and the fingers move at a slower speed when passing the cylinder, and thus operate to strip the sheet. The shaft 112 is preferably driven by eccentric gears, so that the speed of the fingers 110 is slower than that of the cylinder 1 when they are adjacent. The stripped end of the sheet passes down between the bar 106 and discs 109, and is drawn out by the movements of the cylinder and stripper, Fig. 23. The grippers 57 are operated to take and release alternate sheets, when associating, by a cam 56 on an arm 64 on a shaft 66 having an arm 67 operated by a grooved cam 69. When each sheet is to be folded singly, the cam 56 may be locked in position to take every sheet, or in its inoperative position. This is effected by an arm 64<a>, which is locked at 64<b> or 64<c> to the framing. The grippers 57 are closed by an adjustable spring rod arrangement. When each sheet is to be folded singly, the pasting-blade 81 is removed, and a second set of folding-jaws 11, 12 is placed in the recess 4<a>. When associating and folding two sheets without pasting, the pasting-blade or the second set of folding-jaws is rendered inoperative. The various cylinders &c. are driven by gearing, the greater part of which is arranged on one side of the machine. Sheet-carrying pins may be used in place of the grippers 57.
