The wire part of the PM JMC delivers wire tables in this design: longitudinal (multi-wire) with top dewatering former for paper machines with working width up to 7,500 mm and speed up to 1,200 m/min. serves for stock dewatering and consequently it transforms the stock into the “paper sheet“. The stock goes out of the headbox on a longitudinal endless wire where the paper stock is dewatered so that the fibers settle down on the wire surface. 

The endless wire is embraced at the headbox side by a breast roll and on the other side by a suction roll (couch roll) and driving roll. The suction and driving roll combination is recommended for each wire part version both from the drive perspective (better driving force distribution and more cautious influence on the wire itself) and from the perspective of the subsequent paper web removal and its transfer into the press part. In the upper part between the rolls, dewatering elements are located, which have plastic or ceramic foils attached to them. The longitudinal endless wire with the stock is moving on its surface and in case of contact, the stock is dewatered using vacuum.
