補正昭６１．２．１３実用新案登録請求の範囲を次のように補正する
。Amendment February 13, 1981 The scope of claims for utility model registration is amended as follows.

【実用新案登録請求の範囲】刃先間でパイプの絞りを行なう一対の板状の摺
動刃を、相反する方向から刃先が対向する位置に
往復摺動するべく配設し、上記一対の摺動刃の内少なくとも一方の刃先形
状を、摺動始め側の刃幅を広く形成すると共に、
順次刃幅を変えて摺動終り側で、造形する絞り形
状となるように形成した小径パイプ転造装置。[Scope of Claim for Utility Model Registration] A pair of plate-shaped sliding blades for squeezing a pipe between the cutting edges are arranged so as to slide back and forth from opposite directions to positions where the cutting edges face each other , The shape of the cutting edge of at least one of the blades is formed so that the blade width on the sliding start side is wide,
A small-diameter pipe rolling device that sequentially changes the blade width to form a drawing shape at the end of sliding.

Claims

[Scope of Claim for Utility Model Registration] A pair of plate-shaped sliding blades for squeezing a pipe between the cutting edges are arranged so as to slide back and forth from opposite directions to positions where the cutting edges face each other, and each of the above-mentioned sliding blades A small-diameter pipe rolling device in which the blade edge shape is formed so that the width of the blade is wide at the beginning of sliding, and the width of the blade is sequentially changed to form a drawing shape at the end of sliding.
