Abstract

The needle holder comprises a base member 1 of castable or injection-mouldable material having a butt by means of which the holder is mounted in the needle bar 3 of the machine. Steel plates 4 are bonded into the base member 1 in spaced relationship so as to form webs 5 and grooves 6 for receiving the shafts of the knitting needles 7. The holder starts laterally with a whole web and terminates with a whole groove. The edge web 8 bounding the holder laterally is made integral with the member 1 and is therefore rigidly connected thereto. For lateral stabilisation, the web 8 has a projection 10 which extends to the opposite edge of the holder in the form of a strip 11 with similar projections in the grooves 6. Transverse grooves formed in the needle shafts cooperate with the projections 10 to secure the needles 7 longitudinally. <IMAGE>

Description

SPECIFICATION Holder for retaining the knitting needles in a warp knitting machine This invention relates to a holder for retaining the knitting needles in warp knitting machines, the needles being individually retained in respective grooves.

In a warp knitting machine a plurality of knitting needles are arranged one beside the other on the needle bar. In order to retain the knitting needles, it is known to form the needle bar with slots in which the shafts of the knitting needles are mounted. The heavy demands made on the accuracy of pitch and shape of the slots resulted in the abandonment of slotting the needle bar over its whole length; instead, segments known as holders were placed one beside the other on the needle bar.

It is true that the necessary quality was produced by making the slots in the holders, but it was still a very expensive process. For this known reason holders were made of castable or injectionmouldable material and steel plates were bonded into the holders. The steel plates form the webs with intermediate grooves into which the shafts of the knitting needles can be introduced. One disadvantage of this is that the outermost steel plates are inadequately bonded into the holder, since the adjoining castable or injectionmouldable mass of a half groove is too small.

Although they can be manufactured cheaply, such holders have hitherto not been widely adopted.

It is an object of the invention to provide a holder for retaining the knitting needles in warp knitting machines which is made of a castable or injection-mouldable material and has high accuracy of dimension of the webs and the grooves for receiving the needle shafts.

The invention aims at providing a needle holder in which more particularly the edge webs are rigidly connected to the holder basic member.

Accordingly, the present inventon consists in a warp knitting machine a holder for retaining the knitting needles, comprising a base member of a castable or injection-mouldable material having a butt engaging the needle bar, and steel plates which are bonded into the base member and which form webs and grooves for receiving the shafts of the knitting needles, the base member also having means for the longitudinal securing of the knitting needles, characterised in that each holder starts laterally with a whole web and terminates with a whole groove and at least that edge web bounding the holder laterally is made integrally with the holder. The web made integrally with the holder has at least one lateral reinforcement which extends as far as the adjacent web.

Advantageously, the lateral reinforcement is constructed as a projection which co-operates with a transverse groove in the needle shaft which groove secures the knitting needle longitudinally.

Projections made integrally with the holder are preferably each arranged in similar manner between the steel plates, extend beyond the end of the webs, and are constructed as a continuous transverse connection.

In order that the invention may be more readily understood, reference is made to the accompanying drawings which illustrate diagrammatically and by way of example an embodiment thereof, and in which: Fig. 1 is a front elevation of the needle holder with a knitting needle inserted and the associated needle bar, Fig. 2 is a side elevation of the holder illustrated in Fig. 1,and Fig. 3 is a part-sectional view of a detail, taken in the direction of arrow X in Fig. 1, without a knitting needle.

The needle holder comprises a base member 1 of a castable or injection-mouldable material having on one side a butt 2, which engages a needle bar 3. Bonded on the other side into the base member 1 are steel plates 4, so that webs 5 and grooves 6 are produced for receiving the shafts qf knitting needles 7. Each holder starts laterally with a whole web 5 and terminates with a whole groove 6. According to the invention, the edge web 8 bounding the holder laterally is made of the material of the holder, i.e. integral therewith, and is therefore riqidly connected to the holder base member. A number of webs made of the material of the holder can also be provided, in dependence on the fineness of the needle pitch. For lateral stabilisation the web 8 advantageously has at least one lateral reinforcement 9 which extends as far as the adjacent web 4.The lateral reinforcement 9 is constructed as a projection 10 by means of which the knitting needle 7, the shaft of which is formed in known manner with a transverse groove, can be secured in the longitudinal direction. In similar manner the projections 10 are also arranged between the steel plates 5, so that each of the knitting needles can be secured longitudinally. In a particularly advantageous embodiment the projections 10 extend beyond the lower end of the steel plates 4 and are interconnected via a continuous strip-like transverse connection 11.

1. In a warp knitting machine a holder for retaining the knitting needles, comprising a base member of a castable or injection-mouldable material having a butt engaging the needle bar, and steel plates which are bonded into the base member and which form webs and grooves for receiving the shafts of the knitting needles, the base member also having means for the longitudinal securing of the knitting needles, characterised in that each holder starts laterally with a whole web and terminates with a whole groove and at least that edge web bounding the holder laterally is made integrally with the holder.

2. In a warp knitting machine a holder as claimed in claim 1, wherein the web made integrally with the holder has at least one lateral reinforcement which extends as far as the adjacent web.
