Abstract: 23,483. Hoe & Co., R., [Hoe & Co., R.]. Oct. 24. Associating- apparatus; dropping - roller sheet feeds; delivery apparatus; cutting - apparatus; stapling - apparatus. - A machine for associating speciallyprinted inset sheets, and also, if desired, covers, with sheets cut from a web is so arranged that (1) these inset and cover sheets are fed from opposite sides of the path of the main sheets, (2) the inset sheets may be of multi-length and may be severed by cutting-devices and the severed sheets ' superposed before being forwarded to the sheetcollecting cylinder; (3) the inset sheets and the ordinary sheets are taken by separate grippers arranged near together, the grippers for taking the inset sheets being opened prior to the others. As shown, the main sheets are cut by cylinders 3, 4 from a web 1, and are directed by guides 40 and rollers 42 to a collecting - cylinder 36. Inset sheets in single or superposed condition are fed to this cylinder by mechanism comprising rollers 7 and a guide 8, drop rollers 11, 12 carried by arms 13, 14. on a rock-shaft 15; and a registering device 16. A cutting-knife 9 cuts a multi - length sheet in two when two insets are to be fed, and the leading sheet of the two is carried round by grippers 25 on a cylinder 24, and is superposed on the other part. The grippers 25 are operated by a cam 87 movable by a rod 88 and cam on the shaft 35. The cam 87 may be locked so as to retain the grippers open. The inset sheets are directed by a switch 31 to tapes 29 and rollers 39, and are taken by grippers 38 mounted on a shaft 43 fitted with an arm acted on by a cam 45 to open the grippers, the shaft 43 being carried by an arm 47 on a shaft 48 fitted on an arm 49 acted on by a cam 50 to move the grippers to and from the cylinder. A rotating segment 52 holds the inset sheets in the path of the grippers 38, and when the cams 45, 50 cease to act, springs close the grippers 38 on to the sheets. A sheet cut from the web is superposed upon the inset sheets by opening the gripper 39 by a swing cam 55 actuated by a rod 57 and cam on the shaft 35. This sheet is placed over the grippers 38 in register with the inset sheets, and the grippers 38 are freed from the inset sheets and moved on to the top of the associated sheets before another main sheet is associated, by opening the grippers 38 by means of cams 58, 59 similar to the cams 45, 50. When these grippers close on the sheets, they hold them while another sheet is associated. When the desired number of sheets are associated, a cover sheet being supplied by rollers 80, 81 to complete the products if desired, the grippers 39 are opened by a movable cam 60 simultaneously with the opening of the grippers 38 by the cams 58, 59, and grippers 69 on a cylinder 67 forward the product to tapes and a blade 86 folds the associated product. The cam 60 is operated by a cam 64 and lever arms 63, 61, and a cam 72 for opening the grippers 69 is simultaneously brought into operative position. A stapling- mechanism 85 may be fixed on the shaft 65, and staples the sheets on their central lines.
