Abstract: In dwelling treatment apparatus for a textile web through which the web passes in a folded condition, the apparatus having a J shape with an inclined leg and lower arc, the leg is adapted for controlled inclination with respect to the vertical to control the component of force due to the weight of the folds which acts to move the web through the apparatus.

Abstract: A process for the manufacture of flat sheets or webs from a natural fiber material such as cellulose fibers in which the fibers to be processed are first placed on a substrate in the form of a dry heap after which an amount of water not exceeding the amount of moisture which can be absorbed by the fiber is added, whereupon the wetted fibers are subjected to pressure and temperature causing them to bond together forming a sheet or web. When sheets or webs of greater thickness are being made according to the present invention a further step of cooling before relieving pressure is carried out to avoid steam pockets formed within the web from breaking through upon release of pressure.

Abstract: Apparatus for treating textile webs in a treatment fluid such that the material lingers in the treatment fluid for a period of time, in which a support bottom in the form of a trough extending transverse to the textile web and a swinging or oscillating member, having the same curvature as the trough, freely suspended at an eccentric and rotated about an axis parallel to the trough with the direction of the rotation the same as that of the travel direction of the textile web through the trough, form a channel at the beginning of which the textile web is placed in transversal folds and at the end of which the web is drawn off, all of the channel being situated below the fluid level thereby resulting in an improved rinsing action as the web is moved through the channel with the oscillating member aiding in both the rinsing action and in moving the web of material through the channel.

Abstract: A press for exerting a pressure over an area in a longitudinal section of a sheet, particularly a press for producing wood chip board and similar materials, having two opposed pressure plates between which the sheet is passed, and which are braced against respective support structures provided on the outside, wherein the pressure is transmitted by a pressure medium to at least one pressure plate from the support structure associated with it through several pressure elements arranged at points lined up across the sheet in such a manner that a variable pressure profile across the sheet results.

Abstract: In a continuous press having two rotatably driven endless conveyor belts forming opposed, substantially linear spans defining a pressing zone with press platens applying pressure through the travelling spans to work carried therebetween with anti-friction roller means interposed between the platens and spans, the anti-friction roller means being endless loops of rotatably unpowered roller chains forming a bed interposed between the platens and the belt spans with the roller chain spans extending longitudinally with respect to the belt spans and being transversely packed together with each chain individually free to travel independently with respect to the others and the belt span wherein the chains are comprised of units of at least two equal diameter rollers installed in a cantilevered manner on roller pins, the roller pins being linked together by a chain of flat interposed links with adjacent rollers in the direction in which they run of the same length and having their outer end faces situated in a plane

Abstract: A continuous press has two rotatively driven endless conveyor belts forming opposed, substantially linear spans defining a pressing zone, press platens applying pressure through these traveling spans to work carried therebetween, and anti-friction means being interposed between the platens and the spans. Such a press is improved in that the anti-friction means is formed by a multiplicity of endless loops of rotatively unpowered roller chains forming a bed interposed between the platens and the belt spans, the roller chain spans extending longitudinally with respect to the belt spans and being transversely packed together, but each chain being individually free to travel independently with respect to the others and to the belt span. The chains are formed so as to not have a continuous link gap so that the overall path is free from transverse interspacing.

Abstract: Apparatus for drying a traveling web which is permeable to air, has a rotating foraminous drum on which the web is wrapped and screw-type propellers mounted in each end of the drum, the diameters of the propellers closely approaching the inside diameters of the drum. Rotation of the propellers effects suction in the drum. Provision is made for heating air to be sucked through the web into the drum, and optionally for recirculating more or less of the air flowing from the ends of the drum back to the drum's periphery.
