Contactor box for loom

The firing concerns improvements to contactor boxes for looms.

Looms are usually constructed so that there is a shuttle box on each side of the loom, with the archer across the loom's store is beaten alternately into each of the boxes, in which then his movement is braked, so that he again over the Load can be beaten back.

In the contactor box are arrangements for braking the Path of movement of the shuttle is arranged on the loom, usually on the inner surface of the rear and front wall and in some, also babble on the un ~

lower side of the? top wall of the box so "attached are that the movement of the shooter when retracting is braked in the box by catching it while pressing. This braking can be done in that the parts made of brake material a previously set Apply pressure to the side of the shooter, with the contact pressure in some lallen through springs or others Mechanisms is regulated, which the braking material against keep the shooter in contact when entering the East.

When entering the box, the movement of the shooter is delayed by the frictional force exerted on him by the braking material, which is normally the case made of strips of leather, plastic, composite materials or other appropriate ones to brake the movement materials that are suitable for the shooter and do not cause unreasonable wear on the shooter. Leather or other braking material may, depending on the particular Design of the loom, used in a wide variety of shapes and dimensions, is however in usually attached the length of the box and often on the inner surfaces of the rear and front Wall of the box usually made of metal and / or wood attached.

With some shooter brake materials it was found that that the wear at the junction of the box at the point where the shooter "enters the Box first comes into contact with the material, is large.

With the substantial increase in shooter speeds and the use of handmade (man made) materials manufactured contactors, it is becoming more and more difficult to find an ideal material for contactors' brakes to find. Many of the materials used up to now tend to burn or to extreme wear, especially at the junction of the box where the first contact with the shooter takes place. There are new shooter brake materials with greater resistance against burning and wear and tear has been proposed, however, in the area of the inner surface of the main length of the Box itself cause abnormal wear of the shooter's surface, or which has been determined to due to their relatively great hardness or lack of flexibility or are unsuitable for controlled contactor braking for other reasons.

It is the underlying task of the furnace a continuous part made of contactor brake material to attach to both the confluence and the

To create the main length of the box itself, its at the confluence "or the Sdirützeneintrittsseite of the east lying section in one of the treatment of the rest, the remaining length of the protective covering section is treated differently. It is thereby possible in one continuous workpiece made of contactor brake material to treat a predetermined length so that it is used for Covering the junction or the shooter's entry side of the box is suitable, and provide maximum resistance against the starting stop of the shooter there, the remaining length of the material on the other hand is different, the ~ way of treating that they give maximum control of the deceleration with a minimum of wear on the shooter body enables.

The innovation is explained below with reference to the drawings explained in more detail using an exemplary embodiment.

In the drawings shows:

I ¹ Ig. 1 shows a plan view of a shooter S when entering a contactor box, and

]? ig .. 2 is a side view from the direction of the arrow in Fig. 1 on the front contact surface of the box.

tr _

A contactor box, as shown in dash-dotted lines in Fig. 1, has a contactor contact surface a on the front wall of the box and a threshold b on the rear wall, which forms an additional rifle contact area of the box, the front contact surface being screwed to the box and the rear contact surface to an arm B is mounted on a pin b on

2 box is hinged and rests against a lever b which the arm B releases to take up the shooter. This construction is known.

A cover made of brake material G is glued on or otherwise attached to the surface of the bar b or to a brake lining lying on it, and a cover of braking material C is attached to the front abutment surface a in the same way. Similar Covers can be attached to the top and bottom of the box.

The cover material is preferably leather, but can also be made from compositions or plastics or others Materials exist.

The material is made in plate form from tanned leather, with one at the confluence or on Strips to be attached to the box d

with paraffin or wax with a melting point of about 60 ° O or is treated with hard solidifying crystalline waxes "up to a melting point of about 90 °, to create a hard surface that will withstand the first contact with the shooter S. The workpiece plate can then also be coated with wax or treated with wax-like material with a melting point of about 52 ° C "to provide a relatively pliable Section or it can be left untreated. The extra on the relatively yielding Section of applied material does not affect the previously treated hard section.

The brake material can also consist of two through one Junction to a common sheet of material united to be formed in each sections Section the different properties of leather set, the one section being treated so that it forms the hard section.

The cover G for the front surface can be provided with a slot c or a recess for the passage a cooler should be provided, which determines in a known manner that the shooter is running empty.

Protection claims

Claims (2)

1. Rifle box for looms, where the front Braking surface and / or the threshold or rear braking surface with a continuous band of brake material is covered, characterized in that the section (D) the tape (C; G) at the confluence or the entry side of the shooter (S) in the box made of resistant Material is so that it withstands the initial closing of the protection (S) when retracting and that the remaining part of the tape (C, C) properties that one produce good braking effect. 2. Contactor box according to claim 1, characterized in that that the material strip (C, G) over a section (a) of its area with a wax or another Material is treated, which makes the material impact-resistant, while the remaining part of the tape (G, C) is treated with a wax or other material that provides good braking properties. 3 contactor box according to claim 2, characterized in that that a leather band (G, C1) is used as a covering, daiä in a section (a) with a wax with a high melting point above 52 ° 0 "is treated to the To make leather hard, while the remaining part of the belt is not treated or treated differently, so that the leather remains relatively pliable. 4 ·. Contactor box according to Claim 1, characterized in that that the tape (G, 0) strip from two materials one of which (a) is treated to have high impact resistance while the other part is treated so that it has good braking properties, the two partial strips with each other at a junction to a continuous strip of material are connected as a brake lining for the contactor box.
