| 摘要 |
The present invention concerns a suction type gripping device wherein the skirt of the suction-grip is constituted by a deformable pocket of overall annular shape containing particles, the said skirt being provided with means to reduce pressure within the pocket, thereby pressing in the walls of the pocket under higher external pressure to closely conform the pocket with the surface of the article to be gripped, and then retaining that gripping conformity by fixing the said particles in that position after the said skirt has been placed in conforming surface contact with the article to be gripped.
