Abstract: In a knitting machine, a needle position control device comprises knitting needles each having five butts, of which one is fixed and the four others are secured in pairs to two needle latches mounted for oscillation in two recesses formed in the stem of the needle. A selection mechanism acts on the latches so as to move one or the other of their two respective butts out of the guide trick of the needle. By means of this combination of butts, the motion of the needle in the three knitting positions is constantly controlled in both directions of motion of the needle, by moving out two of the three butts. Another embodiment comprising a single latch can give the same result for two knitting positions.

Abstract: Input pulses generated by rotation of a knitting machine are used to produce output pulses that energize needle selection mechanisms therein. A control system operates in such a fashion as to advance the output pulses with respect to the input pulses, while keeping pulse frequency constant. The control system is clocked, and a forward counter is programmed with a number which is dependent upon knitting machine speed, and which number is derived from the number of clock pulses intervening between subsequent input pulses. After the forward counter has been so programmed, it is clocked by the clock until the appropriate number of clock pulses has been counted. At that time, a pulse is generated by reverse counter and a monostable multivibrator, which is used to produce an output pulse according to a program stored in a PROM. Provision is made to bypass the counter when the knitting machine is operated at low speeds.

Abstract: A knitting machine provided with patterning mechanisms responsive to pattern-control signals is caused to produce a non-repeating pattern by generating the pattern-control signals randomly, using a random signal generator not operating in synchronism with machine operation and generating potential pattern-control signals, from which actual pattern-control signals are derived in synchronism with machine operation. Although the pattern-control pulses are randomly generated, the overall character of the pattern produced can be altered by adjustment of the random signal generator to thereby alter the probabilities in the random generation of potential pattern-control signals. Also, pattern restraints are imposed upon the randomly produced pattern-control signals in both the horizontal and vertical directions, involving the number of consecutive stitches of a certain type that are to be permitted to adjoin in one course and in one wale, this being selectable in a manner not detracting from randomness.

Abstract: A circular knitting machine has a needle cylinder and loop-forming instrutalities which form loops along an annular loop-forming zone.

Abstract: The thread storage and supply arrangement comprises a storage drum having a peripheral thread storage surface onto which is to be wound a succession of adjoining turns of thread, the thread storage surface comprising a thread infeed region at one axial end of the storage surface and a thread outfeed region at the other axial end. A thread infeed structure located at the thread infeed region guides thread onto the peripheral storage surface to form a succession of adjoining turns of thread. A thread outfeed structure located at the thread outfeed region feeds off the storage drum thread which is to be pulled off. The peripheral storage surface, at the thread infeed region thereof, curves radially inward in the direction from the infeed to the outfeed region and, at the thread outfeed region thereof, curves radially outward in the direction from the infeed to the outfeed region.
