ABSTRACT:
A fabric-marking apparatus, wherein the upper end portion of a syringe-like or tubular needle for piercing superposed fabric pieces contains an ink pump to which a vertically disposed ink tank is connected; an elastic valve member is fitted in a liquid-tight state between the lower end portion of the cylindrical ink pump and the bottom section of the ink tank; when a plunger concentrically received in said cylindrical ink pump is drawn out therefrom by the descent of the tubular needle, then the elastic valve member allows marking ink to flow from the tank into the cylindrical ink pump; and when the plunger advances into the cylindrical ink pump by the rise of the tubular needle, then a fine aperture formed in the elastic valve member is opened to discharge marking ink from the cylindrical ink pump into the tubular needle.
