A method and an apparatus for marking fabric piles.

摘要

For providing a vertical line marking on the side of a pile of cut out fabric members in order to provide a mark on the edge of all these members it is customary to brand a line mark into the side of the pile by means of a vertical branding wire or edge. For avoiding a number of associated drawbacks the invention prescribes the use of a marking member consisting of an axially slotted tube (6), which is placed with the slot (8) engaging the pile side, this tube being connected with means for injecting into the tube a pulse of pressurized air holding a dyestuff powder, which is thus exhausted through the slot and into the pile side so as to intrude into the edge region of all the single fabric members and thereby provide a visible marking. The upper end of the tube receives a stopper piston (10) having at its lower end a foot member (12) projecting outwardly through the said slot so as to be engageable with the top side of the pile and thus limit the operative length of the slot to the actual height of the pile.
