Abstract
A process is for the production of a padding material (7) made from paper or similar flat structures that are folded together and are formed by tools. At least one intermediate layer (3, 4) is perhaps incorporated within a top layer (2) that is to be folded together. The top layer and the intermediate layer that may or may not be provided are formed along their narrow sides by at least one forming tool (10, 11) after the top layer has been folded together. An intermittent transport unit acts on the structure (1) that is still flat but has been folded together. This causes the structure to be formed longitudinally, in addition to the forming that is carried out by the forming tool (10, 11).
Claims8
Process for the production of a padding material made from a flat structure that is folded together and is formed by tools, comprising the steps of
- folding together a top layer of a flat structure;
- optionally incorporating at least one intermediate layer in said top layer that is folded together, said top layer and said intermediate layer having a narrow end;
- forming the top layer and the intermediate layer that may or may not be provided at each's narrow end by at least one forming tool after the top layer has been folded together;
- and wherein said forming tool indents the structure and causes depressions along side edges of the structure;
- and
- an intermittent transport unit acting on the structure that is still flat but has been folded together and said intermittent transport unit causing the structure to be formed longitudinally in a longitudinal direction, in addition to the forming that is carried out by at least one forming tool;
- and said being formed longitudinally comprising compression applied at right angles to the longitudinal direction.
