Abstract
Abstract Endless elongated loops of metal bands have cooperating linear spans between which a traveling flat workpiece is passed for receiving compression transmitted through the bands. The compression is applied by self-contained presses having platens which span the bands and which are juxtapositioned throughout at least the compression zone, the bands and presses traveling at the traveling speed of the workpiece. On opposite side edges of the bands the presses have mounting side frames provided with means for forcing the platens together. These side frames are separable and at the back end of the compression zone they separate, the platens also separating, the separated press parts being carried back to the front end of the zone where they reengage. Thus, the presses continuously recirculate.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
87 words
A machine for compressing a traveling web while passing through the machine and comprising a plurality of individual presses each having upper and lower platens spanning the top and bottom of the web and means for forcing these platens together on the web, each press having separably connected side frame parts mounting the platens, said parts separating so that the presses may sequentially act on the web in a recirculating manner by separation and reassembly of their side frame parts, while the presses travel with the web.
Claim 2
Dependent Claim
87 words
A machine for compressing a traveling web while passing through the machine and comprising a plurality of individual presses each having upper and lower platens spanning the top and bottom of the web and means for forcing these platens together on the web, each press having separably connected side frame parts mounting the platens, said parts separating so that the presses may sequentially act on the web in a recirculating manner by separation and reassembly of their side frame parts, while the presses travel with the web.
Claim 3
Dependent Claim
58 words
The machine of claim 1 in which said side frame parts are provided with guides which are in the form of elongated loops having linear spans extending lengthwise adjacent the side edges of the web, said guides supporting mainly only the weight of said presses while traveling with the web and of the press parts during recirculation thereof.
Claim 4
Dependent Claim
26 words
The machine of claim 1 in which said side frame parts each comprise interengaging hooks and lugs which engage and disengage by relative transverse motion thereof.
Claim 5
Dependent Claim
26 words
The machine of claim 2 in which said side frame parts each comprise interengaging hooks and lugs which engage and disengage by relative transverse motion thereof.
Claim 6
Dependent Claim
53 words
The machine of claim 2 in which each of said presses is a self-contained press including power-operated means for forcing said platens together and having an operator for this power-operated means, the machine having means for controlling said means as the press travels with the web for turning its power on and off.
Claim 7
Dependent Claim
53 words
The machine of claim 4 in which each of said presses is a self-contained press including power-operated means for forcing said platens together and having an operator for this power-operated means, the machine having means for controlling said means as the press traVels with the web for turning its power on and off.
Claim 8
Dependent Claim
31 words
The machine of claim 1 in which as to each of said presses at least one of said platens has means for supporting it substantially throughout its length on hydraulic liquid.
Claim 9
Dependent Claim
31 words
The machine of claim 6 in which as to each of said presses at least one of said platens has means for supporting it substantially throughout its length on hydraulic liquid.
