Title:
SPREADING AND PLAYING MACHINE
Document Type and Number:
WIPO Patent Application WO/1992/021800
Kind Code:
A1
Abstract:
A fibre web (4) is transported by belts (2, 5) passing around rollers (32-43, 60-69). Some of said rollers are supported by main carriages (10, 14) which are reciprocatingly movable over a bed (8) which moves parallel to the roller axes and receives the web (4) as a mat. Auxiliary carriages (16, 18) are provided to maintain a constant travel length for the belts (2, 5) regardless of the reciprocating movement of the main carriages (10, 14). Each main carriage (10, 14) is connected to an auxiliary carriage by coupling elements (92, 96) which are less extensible than the belts (2, 5) and arranged to be pulled taut by the carriage drive devices (84, 88). Application in the manufacture of nonwovens.
