摘要
The present invention relates to a dispenser in which the expansion of the jaws of the mandrel is automatically obtained by using the weight of the coil, with no external energy supply, by means of a design, inexpensive, simple and without any maintenance, guaranteeing optimum clamping and reproducible bobine.le of the drum (10) comprises a mandrel (20) with a horizontal axis (a), the jaws (21) are expansible by the connecting rods (42) are articulated to the end of a rod (41) and connected to the frame (30) by a connecting rod (44) articulated. It comprises a balance (61) coupled to the frame (30) by a fixed pivot axis (d) and the mandrel (20) by the axis of rotation (a), the two axes (d, a) being parallel. This rocker (61) is arranged to move the core (20) vertically between a raised position for loading and a low position of use under the weight of a coil (1) and to cause the sliding of the tie rod (41), the automatic expansion of the jaws (21) and the automatic locking of the coil (1) .applications: any type of dispenser for coils.
