Product Details

Specifications

Machine for trapezoidal profiles are made of premium quality parts and components, offering a long lasting production solution.

Mill Stand machines are for forming products. Each pair of top and bottom rollshafts is individually carried on sealed for life ball bearings within the adjustable bearing blocks of the individual cast support stand. These blocks are vertically adjustable within the stand for roll height and material gauge gap. The top block adjusting screw is fitted with a graduated display relating to the nip gap between the rolls. The mill stands are supported and key located on base plates which can either be rafted or part of the main fabricated support frame. The frame mounted helical geared motor transmits the drive via gears to the main bottom roll shaft which in turn transmit through idler gears to the remaining bottom shafts.
