Abstract

Abstract In a dual belt press, the press belts are supported at each end by a first chain. The first chain includes spaced links through which a stud projects. A sleeve is mounted on each stud between the spaced links. The outer circumferences of adjacently disposed sleeves abut one another to prevent lateral displacement of the studs and rolls. A second chain is connected to the studs and is adapted to be driven in order to displace the rolls along a press zone of the press.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 112 words
In a dual belt press of the type wherein two belts are each supported by a plurality of rotary rolls, means being provided for supporting each end of said rolls comprising a first chain including spaced chain links spaced apart in a direction parallel to a longitudinal roll axis, a stud passing through said chain links and operably connected to an associated roll, and a sleeve disposed on said stud between said chain links, adjacently disposed ones of said sleeves contacting one another at their circumferences, and a second chain operably connected to said first chain and adapted to be driven for displacing said rolls along a press zone of said press.
Claim 2
Dependent Claim 112 words
In a dual belt press of the type wherein two belts are each supported by a plurality of rotary rolls, means being provided for supporting each end of said rolls comprising a first chain including spaced chain links spaced apart in a direction parallel to a longitudinal roll axis, a stud passing through said chain links and operably connected to an associated roll, and a sleeve disposed on said stud between said chain links, adjacently disposed ones of said sleeves contacting one another at their circumferences, and a second chain operably connected to said first chain and adapted to be driven for displacing said rolls along a press zone of said press.
Claim 3
Dependent Claim 16 words
Apparatus according to claim 1, wherein said second chain is mounted on extensions of said studs.
Claim 4
Dependent Claim 24 words
