MODULE CONSISTING OF CORD AND POLYMER ENVELOPE, MATERIAL OF WHICH CONTAINS ADHESION PROMOTOR Russian patent published in 2014 - IPC D07B1/16 C08J5/10 

FIELD: chemistry.

SUBSTANCE: elongated flexible modules have various applications, for instance, in bearing elements of lifting or cable devices, drive belts for mechanical devices such as, for instance, passenger conveyor or railings for passenger conveyors. Elongated bearing module in form of flat belt for transmission of tractive effort, combined for bearing load suspended by means of said bearing modules, includes: multitude of elongated elements, working for stretching, which support load in longitudinal direction along said elements, working for stretching; and envelope, transmitting tractive effort to multitude of elongated elements, which work for stretching, covering at least part of said multitude of elements, working for stretching, with envelope containing thermally plastic polymer material and melamine-based adhesion intensifier, added into thermally plastic polymer material, which improves adhesion between said multitude of elements, working for stretching, and envelope.

EFFECT: invention makes it possible to increase module strength due to increase of effort required for disconnection of material of envelope and elements.
