Abstract (en)
First and second parallel folding rollers (6 and 7) respectively co-operate with third and fourth folding rollers (4 and 5) of folder means to form first and second folding devices (4, 6 and 5, 7). Non-return feed rollers (8 and 9) are mounted between the first and second folding rollers (6 and 7) for folding pliable strip material (3) alternately to the two folding devices (4, 6 and 5, 7) and an intermediate part (14) of the folder means extends between the third and fourth folding rollers (4 and 5) so as to act as a guide for the pliable strip material (3). Movable guide means (12) are operable to deflect the leading end (24) of the pliable strip material (3) towards the first folding devices (4 and 6).
