Double belt slat conveyor, in other words caterpillar system, its function is to help to get high quality polyurethane foam by keeping the proper temperature and applying or absorbing the pressure.
Caterpillar system is a main part of the whole sandwich panel production line and the production speed will be decided according to its length.
It can be divided into upper and lower mechanically and each part needed own driving system. Because of this, synchronization of both parts is a very important factor to get a high quality of sandwich panels. Also, surface flatness of slat is important, too.
It is possible to adjust the height according to the producing the sandwich panel’s thickness and the side block system will be included to contrast the thrust of polyurethane foam.
