    Abstract: The disclosure describes a straightening machine for lead wires. The machine has concave straightening shoes with complementary shaped straightening rollers supported in closely spaced relation to the concavity of the shoes. The straightening shoes are supported by tension spring which apply a uniform pressure to the bottom of the shoes as the lead wires of the components pass between the rollers and the shoes. A limited travel adjusting screw is disposed in the bottom of the shoes thus providing fine adjustment between the shoes and the rollers. The shoes are made of a dielectric material which will not contaminate the work and is resistant to wear. The straightening surface of the shoes is progressively sloped and this, combined with the variable pressure and clearance adjustment, gives advantages not found in prior machines. No separate means is required for driving the components through the machine since the straightening action also drives the components through the machine. Jamming of the parts in the machine is practically eliminated.

    Abstract translation: 本公开描述了用于引线的矫直机。 该机器具有凹槽矫直鞋，其具有互补形状的矫直辊，其与鞋的凹部紧密地支撑。 矫正鞋由张力弹簧支撑，当部件的导线通过辊和鞋之间时，该弹簧对鞋底施加均匀的压力。 有限的旅行调节螺钉设置在鞋底部，从而在鞋和辊之间提供微调。 鞋子由电介​​质材料制成，不会污染工件并且耐磨损。 鞋子的矫直表面逐渐倾斜，并且结合可变的压力和间隙调整，给出了在现有机器中没有发现的优点。 驱动部件通过机器不需要单独的方法，因为矫直动作也驱动部件通过机器。 实际上消除了机器中部件的干扰。
