    • A cutting head for a glass cutting machine includes a cylinder, a piston movable in the cylinder in one direction to a cutting plane under control of compressed air from a source communicated to the cylinder to act on an upper face and move the piston in opposition to a bias force, a rod attached to and movable with the piston and a cutting wheel carried at the end of the rod for cutting a glass sheet from a glass blank. A port is formed through the wall of the cylinder and means connected to the port responsive to a rapid rise in pressure function rapidly to isolate the cylinder from the source of compressed air and to vent the cylinder. During a cutting operation, the piston seals the port. If the cutting wheel should move beyond the extremes of the glass blank or for any reason move further in the one direction, following movement of the piston shall open the port and the cutting wheel will rapidly retract to and beyond the cutting plane without damage to the cutting wheel.
    • 一种用于玻璃切割机的切割头包括一个圆柱体,一个活塞,该圆柱体在一个方向上可移动到一个切割平面上,在压缩空气的控制下来自一个连通到圆筒的源,作用在上表面上,并使活塞相对于 偏置力,连接到活塞上并与活塞一起移动的杆以及在杆的端部承载的用于从玻璃坯料切割玻璃板的切割轮。 端口通过气缸的壁形成,并且响应于快速上升的压力功能迅速地连接到端口的装置快速地将气缸与压缩空气源隔离并且使气缸排气。 在切割操作期间,活塞密封端口。 如果切割轮应超出玻璃坯料的极限,或者由于任何原因,在一个方向上进一步移动,活塞的运动后应打开端口,切割轮将快速缩回到切割平面并超出切割平面,而不会损坏 切割轮
