摘要:
An arangement for the remote control of the setting of the nip between a fixed roller (57) and an adjustable roller (58) of apparatus which manipulates i.e. folds, slits, scores, perforates or deflects of paper, cardboard or the like, comprises a caliper (64) coupled to the adjustable roller and having a gap (66) the dimension of which varies in accordance with the dimension of the nip. By opening the caliper land inserting a specimen of a sheet in the gap the nip between the rollers is adjusted automatically to suit the specimen. The movable arm (72) of the caliper is formed by a block in which a spindle (73) of the movable roller is journalled and which is moved by a cam (77) operated by a handle acting through a Bowden cable (79).
