Abstract

1315348 Associating apparatus HARRIS-INTERTYPE CORP 13 July 1970 [15 July 1969] 33968/70 Heading B8R In a method of and apparatus for associating a plurality of paper webs P each having longitudinally spaced marginal perforations and extending from a roll R1, the rolls are located in horizontally spaced relationship, e.g. on cantilevered, freely rotatable spindles 14, the webs P being directed, e.g. via tension rods 17, driven rollers 28 and rollers 30, to a corresponding plurality of horizontally spaced feed members 40 having pins for extending into the perforations, the webs P being maintained in spaced relationship from the rolls R1 to the feed members 40, e.g. with the aid of adjustable guide rods 35, the webs then being directed downwardly to be collected in overlapping relationship on an upper run of a substantially horizontal endless conveyer 60 having pins to engage the perforations. A roll R2 of carbon paper may be mounted above each roll R1, the paper web P having glue spots or a line of glue applied by a rotatable brush 34 so that when it meets the carbon paper web C at roller 30, the two webs are fastened together. These web sets may be glued again at 32 to fasten them together when overlapped on the conveyer 60, the web sets being then pressed together by an impact roller 78, transversely perforated at 80 and fed to a zig-zag folder. The rolls R1, R2 may be driven by surface engaging belts 15 subject to the action of a pneumatic brake 20 operated by the tension rods 17. The feed rate of the webs at the feed rollers 40 can be adjusted by manually releasing each roller from connection to its driven shaft (41), Fig. 3 (not shown), and rotating it by hand. This also facilitates the initial registering of the webs and the formation of loops 75 between the rollers and conveyer 60. The webs may be crimped together rather than glued. Preferably, the distance between feed roller axes is less than one half that between roll spindle axes so that web stretching does not cause the pins on the feed rollers 40 to fail to engage the corresponding web perforations. These pins may be retractable.
