Description
y 1956 H. MEIERHOFER DEVICE FOR ARRANGING WIRE HEDDLES ON RODS IN WARP DRAWING MACHINES Filed March 21, 1955 mg n MW M H v j MK w a u United States DEVICE FOR ARRANGING WEE HEDDLES (3N RODS IN WARP DRAWTNG Hugo Meierhofer, Uster, Switzerland, assignor to Hellweger A. G. Apparateund Maschinenfabriiren Uster, Uster, Switzerland, a corporation of Switzerland The present invention relates to a device for arranging heddles made of wire in a row on rods in warp drawing machines.
For mechanically threading the eyelets of wire heddles filed on rods in a loom for weaving, the heddles must be individually presented to the threading device. This is diflicult because the eyelets at the ends of the heddles for receiving the suspension rods are usually formed by a wire loop and by winding the free end of the wire about the adjacent straight portion of the wire. The thickened portion of the heddles produced by the aforesaid winding will henceforth be called the neck of the heddle. Depending on the clearance between the eyelets and the rods extending therethrough, two or more heddles may be positioned side by side, if viewed in the longitudinal direction of the rods. For individually presenting the heddles to the threading device the heddles must be arranged in a row in one plane.
It is an object of the present invention to provide a. device for arranging heddles made of wire and filed on rods on which they are moved relatively to a conventional parting and threading device. According to the invention, a friction wheel is placed on either side of the row of heddles, the wheels rotating in the same direction and laterally engaging one heddle after the other for placing all heddles into the same plane.
The novel features which are considered characteristic of the invention are set forth with particularity in the appended claims. The invention itself however and additional objects and advantages thereof will best be understood from the following description of an embodiment thereof when read in conjunction with the accompanying drawing, in which Fig. 1 is a view of the suspension eyelets of two wire heddles seen in the direction of the longitudinal axis of the suspension rod which is shown in section;
Fig. 2 is a diagrammatic perspective View of the device according to the invention;
Fig. 3 is a diagrammatic large scale perspective part sectional illustration of a portion of the device shown in Fig. 2.
The same numerals designate the same parts in all figures.
Referring more particularly to the drawing, numeral 1 designates a rod for supporting conventional heddles 2 of which two are shown in Fig. 1. The heddles are made of round wire which forms a loop around the rod 1, the end of the wire being wound around the straight portion of the wire, forming the neck of the heddle. The two heddles are placed side by side in a plane which is substantially at a right angle to the plane in which the heddles are normally arranged. This is made possible because the two wires extending upwardly from the neck of Patented May 22, 1956 each heddle to form the suspension eyelet are usually twisted.
In Fig. 2 a staple 4 of heddles 2 is suspended from a rod 1, the heddles 2 being pairwise side by side and on both sides of the plane in which the wire heddles are normally positioned. A brush 6 is supported by two pins 5' which are eccentrically connected with discs 5 which ro tate in counterclockwise direction. Whenever the brush 6 engages the top of the suspension eyelets of the heddles 2, the latter are pushed to the right on the suspension rod 1. The brush 6 and its drive are conventional. Two friction wheels 7 and 8, preferably having a knurled periphery, are driven by bevel gears 18 and 19 to rotate in the same direction. The knurled peripheries of the wheels 7 and 8 may individually laterally engage the necks 3 of the heddles. Below the friction wheels 7 and 8 heddle guide plates 10 and 9 are arranged leaving a slot between the plates which, at the left side of Fig. 2, is so wide that it accommodates two heddle necks side by side transversely to the plane in which the heddles are placed when in normal position. The slot is narrowed adjacent to the friction wheels 7 and 8 so that it can accommodate the heddles only when the latter are placed in a single row, in one plane. The clearance between the friction wheels is somewhat smaller than the width of the slot beneath the wheels.
The operation of the parts of the device forming the subject matter of the invention is diagrammatically illustrated in Fig. 3. The heddles bank up at a conventional parting device 11. When a heddle has been separated by the parting device, the single row heddle staple can be advanced by one heddle. If heddles, for example the heddles 13 and 14, are pushed in pairs against the friction wheels, the knurled circumferential surface of the wheel 7 pushes the neck 13 in backward direction while the knurled circumferential surface of the wheel 8 tends to simultaneously advance the neck 14, assisting the efiect of the brush 6. In this way the juxtapositioned heddles of the staple 4 are placed into a single row 12 in accordance with the advance of the heddles towards the parting device 11.
What is claimed is:
1. A device for arranging wire heddles filed in a row on rods in warp drawing machines, including pushing means for pushing the heddles along the rods, and regulating means disposed on either side of the row formed by the heddles and adapted to laterally engage the heddles, one of said regulating means on one side of said row moving continuously in a direction opposite to the direction in which the heddles are pushed by said pushing means and the other of said regulating means on the other side of said row moving continuously in the same direction in which the heddles are pushed by said pushing means.
2. A device as defined in claim 1, in which said regulating means are formed by two friction wheels rotating in the same angular direction about axes which are parallel to the longitudinal axes of the heddles, one Wheel being placed on one side of the row of heddles and the other wheel being placed on the other side of the row of heddles, the periphery of said wheels being adapted to contact the heddles.
