摘要

The box structure of thermoplastic material for a roller blind, to be installed at a window assembly, is in one piece with a single wall which is extruded continuously and automatically. The box structure of thermoplastic material for a roller blind, to be installed at a window assembly, is in one piece with a single wall which is extruded continuously and automatically. The tunnel-shaped and angled wall sections (1-5) have a number of external and triangular plaster support ribs (6). The open lower edges have lateral members (1a,5a) with vertical secondary profiles (1d,1f) projecting upwards to meet special needs. One lateral member (5a) has a plate structure (5f) to contain thermal or acoustic insulation. The lower leg (5c) forms a narrow groove, to hold an adjustable plaster edge profile.
