Abstract

In a pneumatic gripper for bobbin changer devices with an elastically deformable collar in the gripper housing, the gripper housing (2) and the collar (3) are of bell-shaped construction. The collar (3) is inserted into the gripper housing (2). The collar (3) overlaps the edge (20) of the gripper housing (2) and is pressed airtightly against the edge (20) by means of a screw collar ring (4). The gripper can be produced with a simple construction and cheaply and retains the cop with directional stability.
