PNEUMATIC YARN SPLICING EQUIPMENT

摘要

A slot (33) forming a splicing chamber is closed by sliding action between contacting surfaces of two bodies (23, 9) linked at an axis (7) which is perpendicularly spaced from both surfaces. The closure surface comprises the crown (49) of a piston (48). The piston has a central orifice (51) and is slidable in a bore (47) in one of the bodies to which pressurized air is admitted. When the chamber is closed the orifice registers with the slot and allows a blast of air to pass from the bore into the slot.
