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.
