METHOD OF CROSS CUTTING OF BLANKS OF PRESET LENGTH FROM CONTINUOUSLY MOVING MATERIAL WEB Russian patent published in 2002 - IPC

FIELD: paper-converting industry. SUBSTANCE: invention can be used in corrugated cardboard making lines for cross-cutting of material into blanks of preset length from continuously moving web. Proposed method of cross cutting of blanks comes to directing previously longitudinal cut strips of material to upper and lower zones with cross-cutting devices installed on bed frame. Strips of material are directed to upper and lower zones by means of dividing table with subsequent cutting of material into blanks of preset length by means of upper and lower cross-cutting devices made for angular turning. Cutting members of devices move translationally upwards and downwards in one through vertical slot of dividing table. Several blanks differing in length can be cut off simultaneously using cross-cutting device employed in corrugated cardboard making lines. EFFECT: enlarged operating capabilities. 3 cl, 3 dwg
