Abstract:
In an adjusting device for opposite adjustment of drawing off cam parts of a cam system of a flat knitting machine carriage, with a common stepper motor moving with the machine carriage and providing a rotary movement which is converted into a longitudinal movement of a carriage running direction and transferred to cam parts to be adjusted, with at least one control curve transferring the rotary movement of the stepper motor the cam parts to be adjusted, and with two first control sliders adjustable in the carriage running direction and provided with a toothed strip, a driven pinion of the stepper motor acts simultaneously and oppositely directly on the first control sliders, and at least two second control are each connected with a cam part to be adjusted, with which the first control sliders are drivingly coupled through the control curve in a drawing manner.
Abstract:
In a two-bed flat knitting machine separate sinker control devices are provided for controlling sinkers arranged between needles and have a device body laterally releasably mountable on a machine carriage. They extend only over an operating region of a cam system and their control parts are formed so that they are displaced during a carriage stroke return automatically to an operative position or a rest position.
Abstract:
In a knitting take-off device provided with gripping elements (14) movable through the comb gap of a flat bed knitting machine, the plane of the gripping elements (14) is directed perpendicular to the hooking planes of the knitting needles (13) mounted in the needle beds. As a result, the dimensions of the gripping elements are no longer limited by the width of the comb gap, and the gripping elements (14) can be coupled to additional elements, such as a cover stop rod (16). By means of the cover stop rod (16), the opening (14.2) of the gripping element (14) can be closed and a thread take-up space (20), closable by the head (14.1) of the gripping element (14), can be formed.
Abstract:
The yarn feeder slide proposed for intarsia knitting on a flat knitting machine and provided with a braking device has brake shoes (22,23) projecting sideways on pivoted levers (16,31) and which extend into a special longitudinal slot of the associated yarn feeder rail and can be jammed therein. Two control regions (19,38) for the braking device or for a moveable yarn feeder arm are provided and are spaced from one another in the direction of displacement of the yarn feeder slide (10) so that the yarn feeder driving member located on the cam carriage of the flat knitting machine can be selectively lowered into both control regions (19,38) of the yarn feeder slide.
Abstract:
In the flat knitting machine with a needle selection device, the needles (12) are selected at double selection points and the non-selected needles (12) are locked by means of a locking jack (25) and the control butt (22) of their needle jack (19) is removed from the cam tracks. Force is transmitted to the needle (12) at a special coupling position (23/24) from the control butt (22) of the needle jack (19) articulated to the needle (12), and to increase the control possibilities without provision of additional cam tracks, presser cam elements (57-59), which act on the depressor butts (26) of the locking jacks (25) can be displaced in the plane of the cams. (FIG. 1).
Abstract:
A throttle valve, particularly suited for hydraulic shock absorbers dashpots for motor vehicles, which automatically compensates for a change in the viscosity of the liquid flowing therethrough as a result of a liquid-temperature change. A temperature-responsive expansible ring preferably coacts with resilient valve plates to regulate the flow apertures, and may have either 1* or 2* of freedom of movement in expansion.
Abstract:
A knitted article is produced on a flat knitting machine with a carriage and at least one cam system, wherein the carriage speed is controlled within a knitting row in dependence on pattern types produced by individual needles or needle groups, as well as on the properties of knitting thread or threads continuously so that the carriage at each location of the knitting row is moved with a maximum possible speed at which it is guaranteed that no knitting thread is torn.
Abstract:
In the yarn-delivery device having at least one friction cylinder (11, 12) and at least one pivoting arm (15, 16) for each yarn (20) to be delivered, the pivoting arms having at least one deflecting roller for the yarn are mounted pivotably outside the friction cylinder and are so curved that they are pivotable to behind a friction cylinder (11, 12) and a plurality of pivoting arms (15, 16) for separate yarns (20) can be arranged next to one another. (FIG. 1)
Abstract:
The conventional multiple-spindle automatic lathes are expensive on account of their complicated construction, and the production output and production possibilities are limited on account of the restricted number of work spindles utilized. The novel automatic lathe is to offer higher production outputs and more universal manufacturing possibilities with a simpler construction.The basic structure of an automatic lathe with eight tool spindles (10) for the manufacture of workpieces in eight successive machining stations resides in that, additionally to the number of basic tool stations (1 through 8), each basic tool station, except for the first, is once more included as an additional tool station (2 through 8) arranged in the same sequence of machining upstream of the basic tool stations (1 through 8) so that the total number of machining stations amounts to N=2n-1, a loading and unloading station being provided at the tool station (1). Machining of the workpieces takes place so that each workpiece, after each machining in a tool station, is shifted cyclically in a linear fashion relatively to the subsequent station, and, after seven conveying steps and a subsequent return stroke, or a return stroke between two conveying steps, enters into its initial machining station.The multiple-spindle automatic lathe is usable for mass production of workpieces of a great variety of types.
Abstract:
By the use of special latch needles (21) whose latch (14) can take up two stable positions lying within the limits of its pivotal movement and out of which it can be moved only against the action of a spring, there is ensured, even in fast running flat knitting machines with a transfer mechanism and with stitch presser and/or stitch hold-down elements, and even during the formation of long, loose stitches and loops, reliable trapping of the yarn and manipulation of the stitches and loops by the knitting elements.
