DEVICE FOR CONTACT WELDING OF THERMOPLASTIC MATERIALS Russian patent published in 2018 - IPC B29C65/22 

FIELD: technological processes.

SUBSTANCE: invention relates to devices for contact welding of products made from thermoplastic materials. Technical result is achieved by a device for contact welding of products made of thermoplastic materials, which contains a bed with a table-carriage mounted on it with a drive for horizontal reciprocating movement of the material supply, traverse with brackets on the drive for vertical movement of the removable welding element, electrical devices for monitoring the work and clamps on the frame and traverse. Removable welding element is made in the form of a metal string and is equipped with tensioners at the ends. In the press on the frame, a groove is made, the width of which is equal to the sum of the doubled thickness of the welded material and the thickness of the welding element, and its depth is equal to the sum of the thickness of the welded material and the thickness of the welding element. Clamping on the traverse is made with a concave surface to hold the welding element.

EFFECT: technical result is to increase the strength of the weld, the ability to simultaneously weld and cut the rest of the material.
