  • Stretching device to stretch a film made of synthetic material at least in the transverse direction
    Patent number: 10723062
    Abstract: This stretching device comprises a guide rail, first clamps of a first type and second clamps of a second type each intended to grip the same longitudinal edge of a film and alternately disposed along the guide rail, and an endless chain connected to the first and second clamps and configured to drive the first and second clamps along the guide rail, the endless chain being deformable between a first state and a second state in which the first and second clamps are respectively disposed close to or distant from each other. Each first clamp and each second clamp respectively include a primary guide roller and a secondary guide roller configured to cooperate with the guide rail, the first and second clamps being configured such that when the endless chain is in the first state, the primary guide roller of each first clamp and the secondary guide roller of each second clamp adjacent to said first clamp overlap at least partially.
