Fabric adhesive bonding pressure roller - has mantle with elastic distortion covering hollow zone with pressure fluid between mantle and roller core

摘要

The appts. to give an adhesive bond between two fabrics, such as an outer fabric and a fusible interlining, has a pressure roller (23) with inner fluid pressure and a mantle (26) with elastic distortion. Pref. a hollow zone (37) between the pressure roller (23) and outer mantle (26) takes the pressure fluid. The pressure roller (23) has a fixed core (25) at least partially covered by the cylindrical mantle (26). The hollow zone (37) between them is formed pref. by a necking in the core (25). The opposite ends (35) are bonded in a sealed fit to the roller core (25), in a release mounting. The mantle (26) can be bonded to opposite end sections (27) of the roller core (25), defining the centre necking of the core (25), and with a larger dia. than the necking section. The core end sections (27) have a circular groove (34) round them, to take a clamp to hold the end sections (35) of the mantle (26) in place. The pressure roller (23) has a compressed air supply, opening into the hollow zone (37). The roller mantle (26) at least faces the hollow zone (37) of the roller (23). At least one support is at the outer side of the roller mantle (26), as support rollers, pref. equally distributed round the mantle (26) circumference. The roller mantle (26), with elastic distortion, is a woven carrier coated on both sides with an air impermeable material. The coating is smooth, at least on the outer side of the roller mantle (26). ADVANTAGE - The assembly gives a controlled pressure so that the interlining is securely bonded and the adhesive has penetrated into the outer fabric without any visible exterior signs.
