Drying and shrinking of continuous fabric involves blowing fabric into waves and shrinking it with beaters operating at higher frequency than the waves

摘要

A continuous fabric (1) is transported on an air-permeable sieve conveyor (9) and blown into a waveform (6) by alternate upward (7) and downward (8) air streams. At the same time it is shrunk by the action of beaters (13) on the crest section (11) of the wave. The beating frequency is high compared with the wave frequency. The beater surface can be air permeable and can also include a blowing arrangement. An independent claim is included for the process of shrinking a fabric in waveform by beating at a frequency higher than the wave frequency. The beater can be a mechanically or electro-magnetically reciprocated plunger dish (14) or arranged in the form of rotary beaters.
