Cross cutter by band saw：
Main feature：
1.The perfect cutting unit has to have the cutting speed is synchronized with the panel conveying speed.
2.This cutting unit has to be also operated by the manual or automatic control.
3.The gantry is set at the rear and the saw unit is positioned at the right-hand side as viewed from direction of production. In this position, the band saw blade may also be exchanged.
4.The cross cutter is designed in such a way that the saw band can be changed without production stop since the exchange takes only 1~2 minute. 
5.The double belt line conveys the sandwich panel at a pre-adjusted speed.
6.An incremental encoder is installed at the turning shaft of the double belt measures the length of the endless panel.
7.The pulses are transferred to the microprocessor control of the saw.
8.he band saw waits for the start signal depending on the panel length and then accelerates the X-axle to maximum speed so that the speeds of the endless panel and the band saw are equal.
9. After synchronization of both speeds and offset control, the clamping units are pneumatically actuated to clamp the front and back of panel and then the band saw carries out the first cut from left to right front directionThe saw unit is in motion until the second blade section has also left the cut. The cut panel is lying on a non-driven roller conveyor and is pushed out of the operating area of the saw by the panel coming from behind.The saw unit returns to the starting position at a maximum speed and turns about 180.  At this position the band saw waits for the next start signal (depending on the length of the sandwich panel) and the above described procedure starts again. 
10.Cutting direction is now from right to left.
11.Operating panel is equipped out of housing and Panel can be automatically cut without worker in case the data of panel length and quantity.
12.Automatic or manual work is optional and manual work is used for cutting to a desired length of panel once panel is cut by automatic work.
