摘要： A process for forming a twisted stem tool uses a specially designed clamping jaw fixture at the nose or bight portion of a half-round wire or cotter pin which helps to reduce the required clamping force and distribute that force over the entire wire-fill material interface. The jaws of the clamping fixture engage the outside of the nose over a substantial area, and in some forms actually bite into the wire or pin. After the twisting operation, the stem is placed in a swaging or coining press, and the stem beyond the fill material is reformed into a three or six-sided drive stem. The cold flow of the metal to form the flat sides locks the twisted half round wire or pin sections together so that the stem will resist unwinding if the tool is driven in a reverse direction. The coining of the stem providing flats provides a tighter confinement of the bundle of fill material at the stem, and enables a common three or six jaw Jacob's style chuck, for example, to obtain a more secure grip.
摘要翻译： 用于形成扭转杆工具的工艺使用特殊设计的夹钳夹具在半圆形线或开口销的鼻部或弯曲部分，这有助于减少所需的夹紧力并将该力分布在整个线填充材料界面 。 夹紧夹具的夹爪在大部分区域内与鼻子的外部接合，并且在某些形式中实际上咬入导线或销。 在扭转操作之后，将柄置于模压或压印机中，并将超出填充材料的杆重新形成三个或六面驱动杆。 金属形成平坦侧面的冷流将扭转的半圆形线或销部分锁定在一起，使得如果工具沿相反方向被驱动，则杆将抵抗退绕。 提供平面的杆的压印提供了在杆处的填充材料束的更严格的限制，并且使得例如普通的三或六个爪子雅各布式的卡盘能够获得更安全的抓握。

摘要： An extruded plastic strip contains abrasive grains or minerals embedded homogeneously therein throughout is scored along the machine or extrusion axis direction, such scoring including elliptical or pointed perforations with the long axis or generally pointed ends aligned with the scoring and parallel to the machine or extrusion axis. The preferred plastic material is a 612 nylon, although other plastics may be employed. The material is heat workable, yet relatively stiff and can be used to form a wide variety of power driven abrasive tools. The present application also disclosed a rotary wheel type tool utilizing the perforated strip, and a method of making that tool using a gel type cyanoacrylate as an adhesive. With the strip of the present invention, rotary wheel tools as well as many other tools can economically be produced. In tool use, the strip fractures along the scoring and perforations to provide a tool having closely packed individual rectangular fingers, each with a major flat side facing the direction of rotation.
