Granted: 1989-02-16
Abstract: Method and apparatus for uniformly macroscopically expanding and, if desired, aperturing a plastic web. This is preferably accomplished by supporting the plastic web on a moving three-dimensional forming structure which is supported in a fluid pressure differential zone by a stationary support member. By providing a relationship between the size and pattern of the apertures in the stationary support member and the size and pattern of the apertures in the three-dimensional forming structure, substantially all of the apertures present in the forming structure are unobstructed by the stationary support member at some point during the forming structure's traverse of the fluid pressure differential zone. Thus the resultant plastic web is uniformly debossed and, if desired, apertured in the pattern of the three-dimensional forming structure.

Abstract: Polymers are crosslinked during processing by extrusion, at a temp. between their softening pt. and decompsn. temp., by injecting at one or more positions between the feed and discharge points, a crosslinking agent reactive with the COOH gps. Opt. a blowing agent may be mixed with the polymer to cause foam formation. The copolymer is obtd. from at least 60 (pref. 80-99.9) wt.% of monomers of formula (I) (where G is H or methyl; and Ar is opt. alkyl and halo-ring substd. 6-10C aryl gp.); with one or more comonomers of formula X-C-(CH2)nCOOH (where Z is H, 1-4C alkyl and carboxyl; X is methylene and 2-5C alkenyl, opt. carboxylated (providing X and Z together carry only 1 COOH); and n is 0-4); and a balance, if any of other copolymerisable ethylenic monomers and natural and synthetic elastomers. Crosslinking is effected during processing in a simple one-stage procedure which is esp. suited to the prodn. of very good quality foamed articles by shaping the extrudate e.g. into board, sheet or film or by injection into a mould. Such foams resist collapse at temps. significantly higher than unmodified foams can accommodate. In an example, a styrene-acrylic acid copolymer having wt. ave. mol. wt. 215,000 and contg. 8 wt.% acrylic acid was extruded into expandable beads contg. 14 pts. wt. per 100 of Cl3CF. The granules were re-extruded into foam (die temp. 175 deg.C) using 1% talc as nucleator, and adding 0.11 wt.% of (III). The extruded foam was of excellent quality and had density 4.4 lb/cu.ft. Omitting (III) resulted in a collapsed foam of density 13.6 lb/cu.ft.

Title: Method and apparatus for producing rigid foam panels, especially polyurethane ones
Inventor: ADOLF HERBERT
IPC: B29C44/56
Filed: 1985-12-06
Granted: 1989-08-24
Abstract: The process and the appropriate apparatus for producing rigid foam elements, in particular of polyurethane, operate with a double-belt unit, in which the rigid foam elements produced are provided with upper and lower cover sheets. A parting agent is applied on the lower cover sheet in a particular region in order to permit subsequent removal of the upper cover sheet and the ridge foam in this region, so that the lower cover sheet projects, and foams an overlapping section during subsequent use as a roofing element or the like. The invention permits a very precise cut to be made by means of the sawing apparatus at the end of the double-belt unit, taking into account the application of parting agent at the beginning and, if necessary, the movement of the sawing apparatus itself. This is carried out in principle by a method in which the position at which the parting agent is applied, and the path covered after this application, are input into a computer, which initiates the specified transverse cut after the section provided with parting agent has reached the transverse cut position. When the sawing apparatus itself is movable relative to the foam strand, an additional signal relating to this movement is input into the computer and is also taken into account in the initiation of a transverse cut. The electrical signals for the path covered and, where relevant, the movement of the sawing apparatus are generated by meters, meter for the path advantageously being connected to a tail shaft of the double-belt unit.
