Abstract
The invention relates to a method and a device for the thermal separation of a textile (10) consisting of plastic fibres (9). According to the invention, an impact pulse acts on the textile (10), which is arranged in a single layer between a pair of unheated impact jaws (2, 4), such that the textile is separated and the separation edge (12) is formed, wherein the plastic of the fibres (9) melted during the impact pulse is limited to the region of the separation edge (12).
Claims19
A method for thermally separating a textile (10) consisting of plastic fibers (9), wherein an impact pulse, a stroke movement of at least one of the impact elements (2, 4) extending perpendicularly to the textile (10) with a penetration time of at least one of the impact elements (2, 4) into the textile (10) of less than 10 ms, acts on the textile (10) arranged in at least one layer between a pair of unheated impact elements (2, 4), whereby the textile (10) is separated between the impact elements (2, 4) and a separation edge (12) of bonded plastic fibers (9) is formed;
- characterized in that the opposing impact elements (2, 4) are used in a high-speed, continuous process.
A device for thermally separating a textile (10) consisting of plastic fibers (9), wherein the device (1) comprises a pair of unheated impact elements (2, 4) between which the textile (10) is arranged in at least one layer during the separation process, and further comprises a device for generating a pulse (30), which is configured to introduce an impact pulse into at least one of the impact elements (2, 4);
- characterized in that the first and/or the second impact element (2, 4) are configured and arranged to act in a high-speed, continuous process.
The device according to claim wherein the profiled cross-section (6′) is wedge-shaped with an angle a against the flat effective area of the second impact element (4), the wedge tip of which is designed as radius R3.
