A plate for a separator for the successive seizure and separation of threads held in an array has a leading edge and at least one hook-shaped recess in the leading edge. The recess has a depth in the direction of plate movement which is greater than half the width of the recess. Between a hook tip and the leading edge there extends a fender edge at an angle of 15.degree. to 90.degree. relative to the direction of plate movement. The hook tip is rounded with a radius of up to 10% of the width of the hook-shaped recess.

Plate and separator containing such a plate for seizing and separating

A separator for successively seizing threads held in an array includes a frame, in which at least one plate is guided for seizing the threads. The frame is displaceable toward and away from the array. Each plate carries a piercing needle which pierces the thread for seizing it. Each plate can have two piercing needles disposed at a distance from one another and pointing towards one another.

Separator for seaming machines

The method produces a flat spiral link assembly from at least four synthetic resin monofilament helices wound winding to winding which are simultaneously supplied for meshing engagement. Before being meshed the helices are stretched to at least three times their length and are thermoset in stretched condition. The alternatingly right-hand and left-hand helices are caused to mesh in zipper fashion and are interlocked by pintle wires. In order to facilitate the insertion of the pintle wires the helices are extended by about five percent. The apparatus for performing the method comprises two feed rolls forming a first roll nip through which helices are passed to a heating chamber. Draw-off rolls withdraw the helices from the heating chamber at least at three times the peripheral speed of the feed rolls. The apparatus also comprises a shunt for joining the helices and a device for inserting the pintle wires.
