Clamping cone for accommodating material roll, has clamping elements formed by clamping lamellas, where lamellas sit in clamping position during deviation around rotation axis based on rotation direction or retract into rest position

摘要

The cone has a trunnion (1) for retaining a winding core (9), and clamping elements distributedly arranged at the circumference of the trunnion for transmission of a torque on the winding core. The clamping elements are formed by a group of axially clamping lamellas (2, 2a, 2b) that are arranged one behind the other, where the clamping lamellas are rotatably supported at the trunnion around a rotation axis (3). The clamping lamellas sit in a clamping position during deviation around the rotation axis based on the rotation direction or retract into a rest position.
