Abstract: Process for removing peripheral portions such as bead regions of a glass sheet including a step of pushing the glass sheet in the peripheral portion using a pushing mechanism such as a pushing bar, and corresponding apparatus. As a result of the use of the pushing mechanism, the engagement completion time for suction cups, if used, are reduced significantly. A process without using suction cups is enabled with enhanced yield. The increased process stability and enlarged process window are particularly advantageous for processing glass sheets having high flexibility.

The partially cord-wrapped handle is configured to receive the folding blade when the blade transitions from the locked state into the unlocked state.

Abstract: A scalpel handle for holding a blade includes a handle member and a blade shield for covering the cutting edge of the blade. The blade shield is connected to the handle member for movement relative thereto between a blade-covering position and an out-of-the-way position, and a finger-operable actuator is mounted upon the handle member for movement relative thereto and is connected to the shield so that by moving the actuator between first and second conditions, the shield is moved between its blade-covering and its out-of-the-way positions. An over center spring is interposed between the actuator and the handle member so that upon movement of the actuator into its second condition, the shield is biased into the out-of-the-way position and so that upon movement of the actuator into its first condition, the shield is biased into the blade-covering position.

Abstract: In a circular cutting machine, a main vice unit includes a stationary rear vice and a front vice disposed to be movable back and forth in a range between a position forward of a preset cutting position and a rearmost position where the rear ends of jaws come into contact with the front ends of jaws of the rear vice. The rear and front vices include clamping cylinders that are independently controllable so as to independently clamp and unclamp their respective vices. When photoelectric sensors detect the rear end of work, the remaining length is calculated, which is then divided by the fixed-length feed amount to calculate a remaining number of possible cutting operations. The remaining number of such operations are carried out by using either a combination of the front vice and a transfer vice unit or the front vice alone to pull out the work.
