    • Method and apparatus for trimming plastic frames. Frames are joined to bring heated, soften ends into engagement, causing some softened material to be forced out from between the engaged portions, forming a flashing. This flashing is trimmed by a pair of trimming blades moved along associated guide members. The trimming assembly is mounted directly upon clamps holding the frame members, enabling performance of the trimming operation and eliminating the need for moving to a separate trimming/finishing station remote from the joining equipment. Excellent cutting action is assured by locking the guide blocks preparatory to a trimming operation. Various combinations and sequences of repetitive trimming operations may be selected whereby the cooperating blades are moved in selective cooperating directions to provide a trimming operation which avoids the need for further finishing. Trimming may also be performed simultaneously on multiple stacks of members being joined using the above technique.
    • 修整塑料框架的方法和装置 框架被连接以将加热的软化端部接合,从而使一些软化的材料从被接合部分之间被迫出来,形成闪光。 这个闪烁被一对沿相关引导件移动的修剪刀片修剪。 修剪组件直接安装在夹持框架构件的夹具上,使得能够实现修剪操作的性能,并且不需要移动到远离接合设备的单独的修剪/精加工站。 通过锁定准备进行修边操作的导块来确保优异的切割动作。 可以选择重复修剪操作的各种组合和顺序,由此协作刀片在选择性协作方向上移动以提供修剪操作,从而避免进一步精加工。 也可以使用上述技术在正在连接的多个成员堆上同时执行修剪。
