The workpiece is supported in the horizontal plane and mechanically positioned by a panel pusher for the cuts and held during cutting in position by a pressure beam. The cutting stroke is power driven. Before the cutting stroke commences, the saw blade is automatically raised/lowered and is retracted or out of operation for the return stroke. The cut takes place only in a single straight line (examples see Figures 1 a), 1 b) and 1 c)). The workpiece is loaded manually and / or by means of a powered panel loading device and manually or mechanically unloaded. The machine may have any of the following main features: a) a side pressure device; b) the facility for scoring; c) the facility for cutting post-formed / soft-formed edge pre-cutting; d) a panel turning device; e) a pushing out device; f) pneumatic clamping of the saw blade; g) a powered panel loading device; h) additional cutting line(s) (before front cutting line) located inside the machine e.g. for longitudinal and / or head cut (see Figure 2 and 3.18, 3.19); i) workpiece vacuum clamping as part of a panel turning device or a panel loading device.
