Abstract RU 2507066 C2

FIELD: process engineering.

SUBSTANCE: this invention relates to sandwiched article without symmetry axis and made by compression forming of sandwich portion of fused thermoplastic polymers. Said article comprises feed center corresponding to the point around which said portion is centered inside the mold before compression. Distance between said feed center and article edge referred to as a flow length represents a variable magnitude. For preset flow length, the larger flow length the smaller the mean depth, and vice versa.

EFFECT: better distribution of sandwich structure, particularly, at article ends.
