Abstract:
A knitting machine for clothing has a needle module with a plurality of needle units. Each of the needle units has a needle hook and a plurality of protrusions. The machine also has a first actuation module with a carriage that has a track to connect to one of the protrusions. The carriage can move left and right, and this movement moves the needle units in a longitudinal direction. The machine also has a second actuation module with a connector that has a screw thread to mesh with another one of the protrusions. The connector can move up and down, and this movement moves the needle units.
Abstract:
A clothing-manufacturing knitting machine, and the clothing-manufacturing knitting machine that includes a needle unit including a needle hook formed in an end portion and a protrusion formed in a middle region, a connector including a screw thread formed to mesh with the protrusion of the needle unit, and an actuator configured to actuate the connector to rotate. The needle unit meshing with the screw thread is moved forward or backward as the connector is rotated by the actuator. Accordingly, there is provided a clothing-manufacturing knitting machine with a new actuating system.
Abstract:
A circular knitting machine and a method for knitting an article with such a circular knitting machine, wherein the article is at least partially knitting by a reciprocating rotational movement of a needle cylinder in a forward direction and a backward direction. Needle elements are either being moved in axial direction of the needle cylinder by a stationary cam means according to a predetermined path of a stationary cam means or being moved in axial direction of the needle cylinder by a movable cam according to an amended path or being disengaged from the cam means and movable cam. The movement of each needle element near each movable cam can be individually controlled.
Abstract:
A jacquard pattern control mechanism for a circular knitting machine in which knitting instrumentalities are selected in accordance with a jacquard pattern and are moved between three positions, namely, welt, tuck and knit positions, by a selector jack, a rocker base, a rocker bar pivotally mounted on the rocker base and control cams for controlling the knitting instrumentality, selector jack, rocker base and rocker bar and electromagnetic selection mechanisms that attract selected portions of the rocker bar to determine to which position the knitting instrumentality will be moved, and wherein the selection mechanisms are more compact and have shorter strokes to permit selection of all types of knitting instrumentalities and all three positions without reducing the number of yarn feeds.
Abstract:
The selector has a lower extension for retention by a fixed magnetic selection ring associated with a needle cylinder, and an upper shaped elastic portion for returning the lower portion of the selector towards the outside of a needle cylinder. A flat or inclined profile is defined uppermost on the selector for engagement with a correspondingly flat or inclined base of a sub-needle. A guide portion, having a longitudinal extension lying substantially parallel to the shaped elastic portion, is connected to the shaped elastic portion and is engageable with helical springs used for retaining selectors in needle cylinder grooves. The selector has an upper heel protruding therefrom at an opposite side with respect to said guide portion, and a lower heel extending parallel to the upper heel for engagement with a lifting cam.
Abstract:
Spring jacks are supported for vertical movement in the grooves of the needle cylinder below the needles and select the needles for the control cam to move from the welting position to the knitting or tucking position and to return the needle to the welting position. Jack actuating cams move the spring jacks upwardly to move the needles into operative position with respect to the control cam. The spring jacks are resilient and deflect from an active position to an inactive position out of operative association with an actuating cam. A pattern mechanism selects individual spring jacks in accordance with a predetermined pattern. A selector jack is mounted in each groove in the needle cylinder below the spring jack for limited inward and outward movement and an upper end portion engages a lower end portion of the spring jack. A stack of selector slides operate with the pattern mechanism and each of the selector slides is mounted for individual movement from inactive positions to active positions. Inner end portions are positioned in the path of the selector jacks as they move with the needle cylinder when the slides are in their active position and have an inwardly inclined portion for moving the selector slides inwardly. A horizontal portion maintains the selector jacks in the innermost position for a predetermined time interval. An outwardly inclined portion controls outward movement of the selector jacks and the return of the spring jacks to their active positions.
Abstract:
Needle selecting device (3) of a knitting machine comprised of swinging jacks (5) and further permanent magnets and electromagnets and cams. A pole end (6, 7) of a permanent magnet is selected for each end of the swinging jack (5). The electromagnet pole end (8) is built in least one pole end (6). The push-button (9, 91) is arranged in the space between the pole ends (6, 7) of the permanent magnet to separate one end of the swinging jack (5) from the pole end (6 or 7) of the permanent magnet.
Abstract:
A circular knitting machine of elastic needle type provided with a cam for flexing all the needles into their trick before they are raised to seize the feed yarn, in which the selection between those needles to be maintained flexed and those needles to be allowed to return to their normal configuration is made by axially slidable sliders positioned below each needle contained in the tricks.
Abstract:
A method of knitting an upholstery fabric having at least two adjoined regions of different knitted structures located side-by-side in a wale-wise direction and having courses extending continuously through both regions in which the fabric is knitted with stitches having a first loop length in one region and a second, different loop length in the adjacent region, the loop lengths of the two adjacent regions being relatively adjusted so that, in the relaxed condition of the fabric, the same number of courses in each of the two regions of different knitted structures in the wale-wise direction extend for substantially the same wale-wise distance, so as to give the overall structure a balanced even appearance.
Abstract:
An electromagnetic selector device comprising a single permanent magnet and a plurality of electromagnets, which are excited in contrast or in agreement with the permanent magnet, to form a plurality of selection positions on two fronts along which run the elements to be selected.
