The invention relates to a shuttle with useful inserts on the inside of the longitudinal side parts arranged rib-shaped projections for holding the coil head, which the bearing points of the coil head, one of which is designed to be elastically resilient and where on two bearing points are arranged on a longitudinal side part.

Web shuttle have a central recess, limited by the longitudinal side parts, within which the Coil lies.

It is a web shooter - a so-called pinch shooter - Known, in which a longitudinal side part is slotted so that this longitudinal side part is movable is. A firmly anchored in the shooting wood serves to hold the coil head in place Elastic band for the necessary contact pressure of the slotted long side part on the coil head Takes care »

In this type of shuttle, the spool end is supported on shell-shaped inserts made of plastic that hold the coil head on its circumferential surface from both sides partly to the same extent. ^

The aim is to make the coil head as comprehensive as possible in the region of its longitudinal extent to be stored so that it can withstand the loads that occur when the shuttle moves.

However, it has been shown that even with this mounting of the coil head, the coil at high

209828 / 0A37

Shuttle speeds tend to flutter, which makes it difficult to change bobbins. That is predominantly due to the fact that the coil head only through the elastic band is held, which presses the slotted longitudinal side part against the coil head. The arrangement of the inserts in the shape of a shell in undivided weaving shuttles was therefore not previously possible possible because the bobbin can only be hammered in and out of the shuttle - if at all - under greatest difficulty is possible.

The invention is therefore based on the object of providing a shuttle, in particular an undivided one Weavers to create the weft reel of which is mounted so that on the one hand it is safe when the web clipper is moved is held, but on the other hand a hammering in and out of the web shuttle made possible without great effort. The aim here is to deflect the coil as much as possible to be designed in a straight line so that a trouble-free bobbin change is possible.

This is achieved according to the invention in that one bearing point is in the form of a rib-shaped projection is trained and the one on the other

Side-mounted storage locations - offset from one another with respect to the vertical.

This design of the bearing points ensures on the one hand, a secure holding of the bobbin during the shuttle movement; on the other hand, however, is the force for knocking out the coil not too large, and at the same time the coil is almost straight λ is pushed out the web shuttle.

Another embodiment is characterized by that the one bearing point is designed in the form of a rib-shaped projection on which both sides Connect elastically bendable tabs that rest on the circumference of the coil. This embodiment results in an additional holding effect due to the tabs partially resting on the circumference. on the other hand is also ensured in this embodiment that the insertion and removal of the weft coil With a moderate expenditure of force, because the two sides of the rib-egg-shaped projection subsequent flaps can bend elastically *

According to another embodiment, the one But also bearing point in the form of two ribbed-shaped

formed relatively close to each other whose distance is smaller than the distance between the bearing points on the opposite side.

This embodiment also ensures a safe Holding the weft bobbin during the shuttle movement and ensures that the effort required to turn the coil in and out is not too great will. Here, too, the coil is knocked out almost in a straight line.

The distance between the rib-like projections arranged on one side can be selected in this way be that the intersection of the connecting lines the opposite bearing points are still within the S hat body. Each best spacing of the rib-shaped protrusions on the one hand, with regard to the most favorable expenditure of force when hammering in and out the weft coil can be determined through experiments.

The bearing point on the one hand in all embodiments can be symmetrical with respect to the the other two bearing points are located or offset from this -er symmetry position.

By slight shifts in one of the bearing points With regard to the symmetry to the other bearing points, it is possible to use the most favorable forces in each case to determine the driving in and out of the weft coil can be achieved, for example, by the force for striking the weft coil is greater or less than the force for knocking out the coil.

Several embodiments are shown in the drawing.

Figs. 3 and 4 show other embodiments of the camps.

The shuttle has the long side parts 1 and 2, k the inserts 3 and 4 are arranged on the inner sides. These inserts have the bearing points 5 »6 and 7t the in the form of rib-shaped Projections are formed and which hold the weft spool 10. The bearing point 7 is in relation to FIG the bearings 5 and 6 are designed to be elastically resilient. The inserts 3 and 4 made of plastic of different hardness and hardness are therefore expedient

Manufactured elasticity. In this embodiment, the bearing part J is designed in the form of two rib-shaped projections 7 ^f and 7 ″, the distance between these projections 7'7 ^{11 being} smaller than the distance between the bearing point in the form of rib-shaped projections 8 and 9 on the opposite side .

It is thereby achieved that the weft reel 10 is struck on the one hand with a moderate expenditure of force and can also be knocked out again. The size of the spacing of the protrusions 7 * and 7 * 'in Regarding the distance between the projections 8, 9 can by Trials are determined.

It has been shown, however, that it is useful if the intersection 11 of the connecting lines 12, the opposite bearing points are still within of the shooter's body.

In the embodiment according to FIG. 2, the pre-inspections 7 '"7" lie symmetrically with respect to the projections 8, 9. It is also possible to arrange the projections 7 ", 7" offset on this symmetrical position. As a result, it is possible to vary the force for striking in relation to the force for knocking the weft bobbin out of the shuttle. For example, if the projections are 7 ¹ »7 ^lf in relation to the

209828/0437

Before jumps 8, 9 no longer on the common Axis of symmetry, but are offset, for example, stabbed above, then the force to knock out the bobbin is larger, while the force required to hit the bobbin is smaller.

In the embodiment according to FIG. 3, the bearing point 7a opposite the bearing points 5a and 6a is formed by a single rib-shaped projection Ik , which is expediently symmetrical to the bearing points 5a »6a.

In this embodiment, elastic tabs 15 and 16 adjoin this rib-shaped projection Ik. These elastic flaps have the option of shrinking back when hammering in or knocking out the coil head; on the other hand, they grasp with their outer edges 17 _? 18th

To ensure guidance of the flexible tabs 15 and l6, the Schützeriholz reaches up to the tabs 15 »16.

In the embodiment according to FIG. H , the bearing points 5b »6b and 7b are also provided, which are also formed in the form of rib-shaped projections. One bearing point 7b is arranged on one longitudinal side part and the other two bearing points 5b, 6b are arranged on the opposite longitudinal side part.

In this embodiment, one bearing point is 6b arranged offset with respect to the other bearing point 5b.

In the embodiments according ^{to FIGS. 3 and} 3, too, the opposite bearing points can be arranged symmetrically or offset with respect to the symmetry position.

In order to be able to regulate the contact pressure of the bearings sh, a slot 22 is attached at the end of the central recess 21 in the longitudinal direction of the shooter, the width of which can be regulated by a clamping screw 2J , which is arranged transversely to the slot and is firmly stored in the shooter's wood.
