ABSTRACT:
In a compact frame assembly for a press having a top roll (5) and a bottom roll (4), the ends of which are supported in bearing housing members, each bearing housing member (16) for the bottom roll (4) has a head portion (53) of substantially T-shaped cross section, and each bearing housing member (17) for the top roll (5) has a foot portion (54) of inverted substantially T-shaped cross section. The foot portion stands on the head portion, and two sturdy channel bars (34, 35) are pivotally mounted laterally of the head portion and the foot portion, one on each side. The channel bars may be swung into clamping engagement with the cross bars (55) of the two tees to connect the head portion (53) to the foot portion (54). One of the rolls may be a shoe type press roll (4) having a flexible roll shell (11), and preferably the bearing housing members (16) of that roll have the basic shape of circular disks of a diameter that is smaller than the diameter of the flexible shell (11) to facilitate an exchange of the flexible shell.
