ABSTRACT:
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, a marking member is used which includes an axially slotted tube placed with a slot thereof engaging the pile side. The tube is connected with an injector 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 having at its lower end a foot member projecting outwardly through the 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.
