摘要:
A home knitting machine is provided with a reader for reading out patterning instructions on a programmed card, an electronic memory for storing signals read from the card, means enabling an operator to select a needle to knit a particular column of a design unit and to thereby fix the overall position of a design in a width of fabric to be knit, and means for recalling the stored signals from the memory in synchronization with movement of the carriage during knitting and for causing the operations of needle selectors on the carriage in accordance with the recalled signals.

A program reading apparatus in a knitting machine including a movable reading head adapted to scan a program carrier having thereon patterning instructions for control of the pattern to be knitted on the machine. Means are provided therein for preventing rebound of the reading head upon arrival at or return to its starting position, such means being operated by the momentum of the reading head upon reading head arrival or return to momentarily arrest the reading head at the starting position.

A patterning device employs an elongated strip which is fixed between an operating element, such as a guide bar of a warp knitting machine, and a fixed support point. In addition, the patterning device has a displacing element in the form of a rotatable eccentric or a reciprocally mounted roller which is used to deflect the strip between two points intermediately of the length of the strip so as to exert a pulling force on the guide bar. The amount of deflection of the strip determines the amount of movement of the guide bar. The guide bar can be returned by way of a spring or by a second strip which is deflected in similar manner as the first strip by a displacing element. In one embodiment, a single displacing element is used for deflecting purposes while in other embodiments, a multiplicity of displacing elements are used. The strips may be attached directly to the guide bar or indirectly, for example, over a pivotally mounted lever.
摘要:
A weft feeler device for a loom comprising a movable assembly sychronously oscillatable with the loom and carrying a sliding unit on which is mounted a feeler, subjected to the retaining effect of a weft, and a screen. The assembly carries a photo-electric system comprising an optical beam generator and a photo-electric sensor. Upon breakage of a weft thread, the slidable unit is not retained and the screen occupies a position in which it blocks the optical beam.

A home knitting machine is provided with electronic control means which function pursuant to patterning instructions on a program card and in response to the operation of control devices by an operator causing needle actuators on the carriage of the machine to be selectively operated and fabric knitted in a prescribed manner on the machine.
摘要:
A method and apparatus for controlling needles of a knitting machine based upon comparing a plurality of predetermined position control patterns defining target positions with the position of a yarn feeder and a needle. When the positions are not the same, each needle is incrementally moved based upon the present position of the needle and the determined target position of the needle.

As the carriage of a flatbed knitting machine traverses the needle bed, a lse generator which comprises a toothed disc and two cycle signallers at its circumference produces pulses in synchronism with the carriage movement and corresponding to the needle cycle for electronic control of the machine. The toothed disc has a tooth pitch which corresponds in whole number multiples with the pitch of the needles in the bed. The pulse generator may be located on the machine frame or on the carriage. In the former case the carriage can have a pick-up which entrains a chain stretched on the machine frame with the toothed disc rotatable jointly with one of the sprocket wheels for the chain. In the latter case the toothed disc, carried by the carriage may be rotated by a coupled pinion which meshes with a rack stationary on the frame and co-extensive with the traverse of the carriage. In each case the pulse generator produces synchronized control pulses without direct scanning of the needles in the bed.
摘要:
Operation conditions of a knitting machine for respective courses are marked on predetermined columns of a program sheet and are thus stored, the program sheet is rotated in the normal direction or reverse direction by one pitch per course, and marks are read out at every step of the program sheet by a mark reader to operate the knitting machine under conditions indicated by the read marks. In the apparatus for saving instuctions of a program sheet according to the present invention, when the operation of a knitting machine is continuously conducted under the same conditions, the stepwise advance of the program sheet is stopped and when the operation of the knitting machine is repeated according to a certain operation cycle, the program sheet is rotated in the normal direction or reverse direction according to said operation cycle.
摘要:
An input device for providing signals for controlling a knitting machine. The device includes a mechanical information storage means and a switch means responsive to the contents of the storage means to provide a signal corresponding to the stored information. The storage means is disposed for operation either manually by a machine operator or electromechanically in response to instructions provided by other components of the machine. The device is incorporated in a program reading apparatus to specify feeding direction of the program carrier on the knitting machine.
