    摘要： A paper corner trimmer includes a first blade having an extension extending perpendicularly from a side thereof and a second blade is engaged with a shaft which extends through the extension. A torsion spring is mounted to the shaft and two legs of the spring respectively engage with the two blades. The second blade is slightly curved so that an angle is maintained between the two blades. Two positions on two ends of the cutting edge of the second blade are respectively stopped by two stop points on the first blade when the second blade is located at its two extreme positions.

    摘要： The invention relates to a mechanism for adjusting the feed length of a rack and pinion roll feed mechanism of the type generally used for feeding strip stock into presses. The feed length adjusting mechanism comprises a hub member connected to the press shaft, a throw block connected to the hub, and a slide rotatably connected to the connecting rod of the rack and pinion drive for the feed. A slide is locked to the block by means of a piston and cylinder lock mechanism, and a lead screw is threadedly connected to the slide and rotated by a bidirectional pneumatic motor mounted to the block, whereby rotation of the lead screw causes the slide to translate within the slideway. This changes the length of the eccentric connection between the rotating block and connecting rod thereby proportionately changing its stroke and the amount of strip stock which is fed into the press during each cycle of the feed mechanism. A fluid union mounted to the adjustment mechanism supplies pressurized air to operate the lock mechanism and the pneumatic motor.
