| 摘要 |
The invention relates to a rotary stapling machine that comprises a first rotatable roller (2), means (6) co-acting with said roller (2) for holding a U-shaped staple (7) in a predetermined position of orientation, a second rotatable roller (3), and a so-called pad unit (8') for co-action with said second roller (3). The rotatable rollers (2, 3) are adapted to rotate at a peripheral speed which will allow material (1') to be stapled to pass therebetween. Pressing of the staple legs through the material (1') and bending of the staple legs takes place as the material (1) moves between the rotatable rollers. The material (1') passes the first roller (2) so that the staple legs (7a, 7b) will be able to penetrate the material or be pressed therethrough. The pad unit (8') is adapted to receive the legs (7a, 7b), and leg-bending devices (31, 32) function to press the legs together through the medium of mutually opposite forces that act in a plane corresponding to a plane of the staple (7, 7a, 7b, 7c). |
