Machine and method for manufacture of a sheet of single-face corrugated

Machine and process for making a sheet of single face corrugated

Cardboard box forming and printing machine on which it is possible to effect a change of block on the printers without loss of time detrimental to the output of the machine. The printing modules of the machine are equipped to enable lateral translation either of the block-holder cylinder alone, or of the unit constituted by the block-holder cylinder and its inking device, as well as retractable means for propelling the cardboard which can be positioned when the block-holder cylinder is retracted laterally so as to continue to ensure the operation of advancing the cardboard provided by the latter before its lateral retraction.

Retractable propulsion apparatus for cardboard box printing machine

In a cardboard blank folding machine for folding up the extreme transverse panels of a blank, e.g. for a carton, along longitudinal fold lines, and comprising a pair of longitudinal beams whose spacing is adjustable in dependence on the spacing of said fold lines, a pair of lateral elements whose spacing relative to said longitudinal beams is adjustable in dependence on the transverse dimensions of said extreme transverse panels, and a pair of folding bars each forming a longitudinally extending ramp for forcing said extreme transverse panels to fold about said fold lines as said blank passes along said machine, the improvement wherein said folding bars are each supported at the upstream end on a support fixed to said corresponding lateral element and at the downstream end on a support which is vertically movable in a guide supported by said corresponding beam, and vertical displacement of each said downstream support is directly and proportionally tied to transverse displacement of said corresponding lateral element relative to said corresponding beam.
