Abstract
A sequential cleaning device for a loom ensures sequential cleaning by blowing compressed air or possibly by suction, at various points of a loom. The device comprises, upstream of a utilization circuit leading to various points to be cleaned, a pneumatic control circuit connected to a compressed air inlet. The circuit comprises, in a main pneumatic line a first distributor which is normally closed, and controlled mechanically and a second distributor which is normally open and controlled pneumatically. Controlling the opening of the first distributor may be effected by a rotary member forming a cam of the loom. Controlling the closure of the second distributor is ensured by a branch supply line in which pneumatic delay means are incorporated.
