Abstract

1321761 Web feeding for selective printers INTERNATIONAL COMPUTERS Ltd 26 March 1971 8235/71 Heading B6F Transverse positioning of tractor feeds.-Each tractor 13 of a pair is mounted on its own elongated bar 21 or 22 provided with cooperating positions 23 such as slots, grooves or holes for coarse positioning. The bars 21 and 22 are slidable in the machine frame 16, 17 by drive means which includes a first coupling for producing similar axial movement of both bars 21 and 22 together and a second coupling for producing axial movement of one of the bars separately. The drive means includes a rotatable axially movable shaft 28 of which a first portion 32 has spaced circular grooves and a second portion 27 has a spiral groove, the portions meshing with a co-operatingly cut first and second pinion, 33 and 30, respectively. Rack and pinion action at the first portion 32 on rotation of the first pinion 33 causes axial movement of the shaft 28 which by rack-andpinion action at the second portion 27, causes simultaneous rotation of the second pinion. This causes movement of both tractors when knob 38 is rotated. Straight cut of the first pinion 33 and co-operating first portion grooves 32 allows rotation of the shaft 28 to drive only the second pinion 30. This causes movement only of bar 22 and therefore one tractor 13 when knob 31 is rotated.
