Abstract: 23,482. Hoe & Co., R., [Hoe & Co., R.]. Oct. 24. Associating - apparatus; delivery apparatus; stapling-apparatus.-A machine for associating sheets cut from a web with specially - printed sheets to form insets is so arranged that the inset sheets may be placed centrally inside the ordinary sheets, or between them in other positions, or with one inset placed centrally and another, other than centrally, inside the other sheets. The sheets are assembled on a collecting-cylinder, and the inset sheets are fed from the collecting-cylinder side of the path of the ordinary sheets. A cover may be applied to the collected product and the whole secured together by stapling &c. As shown, the ordinary sheets are cut by cylinders 3, and pass to feeding- cylinders 35, 36 which also receive sheets fed from the sheet-feeding mechanism shown on the left of the Figure and comprising feed-rollers 6, 7, drop-rollers 8, 10, and a registering-stop 16 situated in front of transverse cutters 12, 13 which sever sheets of multi-length when these are used. The cylinders 35, 36 are driven slightly faster than the means for forwarding the inset sheets, and a recess 37 is formed in the cylinder 35 enabling one set of sheets to be pulled away slightly from the following set. A guide 18 directs the sheets to rollers 12, 22, and, when two parts of a sheet cut from a multi-length sheet are to be superposed, the leading end of the sheet is tucked by a blade 23 on the roll 22 into a nipping-jaw 20 on the roll 19, a cam-actuated guide 24 being used to ensure the gripping of the sheet by the jaw 20. This jaw carries the sheet round and superposes it in register on the second sheet cut from the multi-length sheet. A roller 30 assists in forwarding the sheet when freed from the jaw 20. The superposed sheets pass to rolls 34, 35, and are associated while passing through the rolls 35, 36 with a sheet cut by the cylinders 3. The sheets pass to a collecting-cylinder 38, and are taken by grippers 40 on spring-controlled arms 41 controlled by a cam 43 to open the grippers for receiving the sheets and permitting them to close on the sheets. These sheets are placed over other similar grippers 44 which remain closed while passing the sheet-receiving position, and these grippers are removed from beneath the sheets by a cam 49 while passing the delivery position, and close on the sheets to hold them in position while other sheets are being received by the grippers 40. A second inset sheet or sheets and other ordinary sheets may be associated with those already received by the grippers 40, and a cover sheet fed by rollers 56, 57 may be applied to the outside of the associated product. The completed product is stapled by a device 60 on a cylinder 59, is delivered by grippers 51 on a cylinder 50, and is directed by tapes 54 and a guide 55 to a reciprocating folding-blade 61. Both sets of grippers 40, 44 are opened by a swinging cam at the delivery position. In a modification, the rolls 19, 22 are dispensed with, and when two inset sheets are to be superposed, an oscillating guide directs one sheet to a path which is longer than the path to which the succeeding sheet is directed and the two are associated in register and forwarded to rolls similar to the rolls 35, 36.
