METHOD AND DEVICE FOR REINFORCING AND/OR LINING MATERIAL Russian patent published in 2018 - IPC B29C65/08 B29C65/34 B29C65/74 F16B5/01 B29C65/14 B29C65/16 B29C65/18 

FIELD: plastic processing.

SUBSTANCE: group of inventions relates to a method and device for reinforcing and/or lining (embodiments), and a unit for reinforcing a porous material. In accordance with the method, a thermoplastic reinforcement and/or lining element is subject to mechanical energy impact and mechanical pressure by a tool so that reinforcement and/or lining material of the reinforcement and/or lining element is liquefied and pressed into porous material to reinforce the porous material. In at least one axial depth, the reinforcement and/or lining element is segmented as a function of the circumferential angle so that at this axial depth the circumferential wall of the initial opening in first regions is in contact with the reinforcement and/or lining element, and in second regions is not in contact with the reinforcement and/or lining element.

EFFECT: technical result achieved by the use of a group of inventions consists in improved anchoring stability of screws or other joining elements in porous material.
