Abstract: A rotary envelope machine blank cutter is provided with laterally adjustable, independent frame units for each meshing set of knife rolls for changing the depth of a side cut into a blank for envelope size and style production changes. The rotational and axial meshing of hard and soft knives respective to a single knife roll set is adjusted without disturbing the roll mount of either knife. Changes in envelope length or style are accommodated by the mechanical capacity to adjust the rotation cut timing between the knife roll sets of a two-set unit and also between respective cutting units of two or more two-set units. As in the case of lateral cut adjustments, knife roll mounts are undisturbed by rotational timing adjustments. Consequently, the machine may be quickly and accurately changed for production runs of any of several envelope style and several sizes respective to each style: all adjustments being made without disturbing the knife profile mesh of any knife set.

Abstract: The leading end of an intermittently fed flattened tubular web is clamped by a gripper, whereupon a severing mechanism cuts a section from the web. The gripper advances the leading end of the tube section before the trailing end has cleared a pair of clamping rollers and while a folding roller engages an intermediate portion of the section and moves it laterally to form a loop in the tube section before the latter is discharged transversely.

Abstract: A method of and apparatus for producing discrete blanks from a web of foil or the like lis provided, in which the foil or the like are given continuous constrained guidance during the phase between separation of the web until transfer to a packet or packing machine. Severance from the web is carried out in at least one initial cut, followed by a main cut, during continuous constrained guidance.
