| 摘要 |
The invention relates to a device for opening of bag-like bodies of tubular form, opened at least from one of their ends, with at least one slide, inserted between the walls of the bag-like body for bending. The device improves the reliability, reduces the power consumption and the technical servicing time, thus increasing its productivity. The device includes at least one slide (3), moved inside-outside in the open end of the bag-like body (2, 2a) by at least one moving cam (9) running along a preset guiding line (38), meshed in slide (3). The latter is moved along the guiding line (4), parallel to the direction of the transportation of the bag-like bodies(2, 2a), travelling on the conveyor (1). The speed of transportation of the bag-like bodies (2, 2a) on the conveyor (1) and that of the slide (3) along the guiding line (4) are equal. 15 claims, 2 figures |
