Saw aggregates in spindle moulders appear in two different versions:

• Cut off saw for cutting tenons
• Glass bead saw for longitudinal profiling

1. Cut off saw

This kind of saw aggregate can be found frequently in older spindle moulders. In connection with a roller table they make the spindle moulder a full-fledged tenoning machine.

2. glass bead saw

More recent spindle moulders in contrast are equipped with a glass bead saw. Within the moulding process its task is the dissection of the glass bead from the window scantlings. The aggregate is located to the left of the router head, so the cutting occurs immediatly after the profiling. A riving knife acting from above is used to seperate scantling and batten.

During the tenoning the glass bead saw aggregate is not necessary. Therefor it can be restracted sideways or backwards. The manufacturer Casolin optimized the retrofitting process from crosswise to lengthwise processing in its model F90-K in a way, which enables the fitting of all required devices in 20 seconds without any assembling works caused by traversing and swiveling movements. Other manufacturers offer assembling and roller table concepts that greatly facilitate the production of windows on spindle moulders.

The glass beams can be cut out also on a moulder, an outside profiling and moulding machine or an angular window machining centre during the moulding process; see also glass bead trimsaw.
