Abstract
A coupling construction between an extended-nip roll including a non-revolving central axle supported by bearings which permit angular deflection of the non-revolving axle and a backup roll. Loading members are mounted on the non-revolving axle for pressing a loading shoe toward the backup roll. The extended-nip roll includes a flexible glide-belt mantle whereby a paper web or board web passes through the nip between the glide-belt mantle and the backup roll. The belt mantle revolves on support of separate bearings. The extended-nip roll and backup roll are interconnected from the bearing housings at the ends of the rolls by tie bolts which include a nut at one end which is threaded onto the threading at the end of the tie bolt. The tie bolt is associated with pre-tightening equipment at the other end of the tie bolt and is passed through bolt holes provided in the bearing housings to be coupled together. The other end of the tie bolt has the threading with which the pre-tightening equipment is coupled.
