A method for producing lining panels which can be removably attached to a surface.

摘要

A method of producing large area lining panels (1) composed of thermoplastic material which are used as removable linings for containers. On the rear of the lining panels (1) there are arranged next to each other in rows a plurality of affixing knobs (2) also made of thermoplastic material which have a circular or polygonal cross-section with conically inclined surface portions. A plurality of the affixing knobs (2) are simultaneously palced on the lining panel (1) and joined to it by ultrasonic, vibratory or rotational welding. The placing and welding of the affixing knobs (2) singly or in groups at a predetermined distance from each other is effected in a continuous succession.
