【考案の詳細な説明】
本考案はべら針を使用する高速度シンカトツプ
編機用のシンカに関するものである。[Detailed Description of the Invention] The present invention relates to a sinker for a high-speed sinker top knitting machine using latch needles.
周知のように、シンカは、編機のべら針が編成
動作を行なつている時にはこのべら針の頭部から
編糸を容易に脱出させ、べら針の上昇時にはべら
針内の編糸の上昇を防止し開かれたべらの先端か
ら編糸を脱落させる。このようにして、シンカは
べら針のループの形成を容易かつ確実なものにす
るのである。 As is well known, the sinker allows the knitting yarn to easily escape from the head of the latch needle of the knitting machine when the latch needle is performing knitting operation, and when the latch needle is rising, the sinker allows the knitting yarn inside the latch needle to rise. This prevents the knitting yarn from falling off from the tip of the opened latch. In this way, the sinker facilitates and reliably forms the loop of the latch needle.

である。 Incidentally, in recent years, in order to improve productivity, it has been required to rapidly increase the operating rotational speed of knitting machines. This has led to new problems with the sinker that did not occur with conventional rotational speeds. That is, there is a problem of wear and breakage of the sinker due to contact between the sinker and the reciprocating motion control cam of the sinker. The possible causes of this problem are that as the rotational speed of the knitting machine increases, a strong impact force is applied to the sinker at the transition point of the sinker's reciprocating motion, and that the sinker guide groove and control The sliding speed with the cam becomes extremely high, increasing the resistance force.
本考案は、上記２原因の軽減を図ることにより
シンカの磨耗・折損を防止することを目的とす
る。 The present invention aims to prevent wear and breakage of the sinker by reducing the above two causes.

の少なくとも25％を軽減させることである。 The sinker of the present invention consists of a front part having a nose and a rear part having a control cam contact protrusion. It is characterized by a notch provided at the lower edge. Particular preference is given to providing elasticity in the height direction of the sinker and a reduction of at least 25% of the total weight by means of this partial reduction and cutout.

用上差支えない結果となつた。 First of all, the weight is significantly reduced, and since it has elasticity in the height direction, the impact force at the transition point of the sinker reciprocating motion during high-speed operation of the knitting machine can be alleviated. Furthermore, since the length of contact with the sinker guide groove is significantly reduced, sliding resistance can be reduced. As a result, the sinker of the present invention saves labor during high-speed operation, and reduces damage and wear of the sinker. In particular, when the weight of the sinker is reduced by 25% or more as in this example, breakage of the sinker becomes almost non-existent, and wear on the sinker can be reduced to about 1/2 compared to the conventional type, making it possible to reduce the weight of the sinker by more than 25%. The result was that there is no problem in practical use as a sinker.
