Filed:

Nov 4, 1974

Appl. No.:

5/520417

Inventors:

Juan Vinas - Brooklyn NY

Assignee:

Vinatex Knitting Systems, Inc. - Brooklyn NY

International Classification:

D04B 900

US Classification:

66 50R

Abstract:

A selection device for knitting machines having a rotating cylinder with slots around its circumference for accomodating a knitting needle and an associated knitting jack in each slot, the device including a selection tape loop for controlling the jack selectors of the knitting machine. The jack selectors are movable between an operative jack position and a non-operative jack position. Stationary detecting elements co-act with the tape loop for determining the positions of the jack selectors to provide a predetermined knitting pattern. A drive mechanism moves the tape loop in synchronization with the cylinder and relative to the stationary detecting element. Cam elements are provided for moving each of the needle jacks in the operative jack position along its slot into engagement with its associated knitting needle to move the associated knitting needle into an active position for knitting the desired pattern, whereby the needles associated with each of the needle jacks in the non-operative jack position remain in their respective slots and are nonoperative during knitting. Control holes are also provided in the tape loop for coacting with a disengagement mechanism for stopping the drive mechanism at a predetermined time.

Abstract:

A multi-purpose yarn feeding device for knitting machines is described which includes a number of co-axially arranged rotary members which correspond to the number of yarns fed to the respective feeding station, each rotary member being provided with a frictionally yarn engaging circumferential periphery. Adjustably positionable eyelet guides are arranged to guide the incoming yarns towards and guide the outgoing yarns from the circumferential peripheries of the associated rotary members to result in yarn portions being in contact with preselected arcuate lengths of the circumferential periphery to thereby impart selected tractions to the yarns. A spring member having a fixed end and a hook for engaging a yarn portion is movable generally in the plane of an associated rotary member for selectively pulling away the yarn portion from the associated circumferential periphery of the rotary member. This modifies the extent of contact with the circumferential peripheries responsive to the tensions in the yarns to thereby modify the degrees of tractions imparted to the yarns and compensate for the externally applied tensions to the yarns. The feeding device can be used as a positive or compensating feeder for stripers and compensator feeder for Jaquards.

Abstract:

Electrically actuated jack selectors for a knitting machine which are normally positioned out of engagement with the needle jacks or pattern jacks of the knitting machine. When each of the jack selectors is actuated, either by a perforated tape loop or by a drum, the jack selector is deflected into a position along the path of an associated needle jack or pattern jack and, upon engagement therewith, displaces the associated jack relative to the cylinder so that, depending upon the direction of deflection of the jack selector, either the needle jack or the pattern jack will not be raised by the cylinder cam. Each jack selector includes a knife edge cam portion that is engaged by a conically shaped tip on the movable armature of a solenoid that is associated therewith. A comb-like element may be used to initially position a group of the jack selectors in order to predetermine the direction of deflection thereof. The teeth of the comb-like element, between which the jack selectors are positioned, also limit the angular deflection of the jack selectors.
