Title: Shortened guide path installation for extruded tubular film mfr. - uses flattening squeeze rollers immediately after the blowing step, and any desired number of guide rollers
IPC: B29C48/10
Filed: 1974-01-24
Abstract: In a foil guide installation in extrusion plant for mfr. of tubular film, the path from the extruder to the flattening squeeze stage is long enough to allow the film to cool whilst being more space-saving than prior-art equipment. This is achieved by flattening the extrudate immediately after the blowing stage, using squeeze rollers, and then diverting its path any desired number of times, with the aid of guide (deviating) rollers. Spec. the film may be held or conveyed flattened, after each diversion, with the aid of rollers adapted to hold it in flattened condition. The air pressure in the tubular film may be maintained constant from the extrusion stage to the final flattening squeeze stage. Alternatively, the air pressure may be selectively varied in in the various flattening stages either by varying the nips of the squeeze rollers or by making holes into the film.

Title: Internally corrugated packaging sheet with all round stiffness - obtd by internal ribs in different directions in different layers
Inventor: SAKURAI MASAO
IPC: B32B27/00
Filed: 1974-05-08
Abstract: A composite plate of thermoplastics is constituted of two parallel outer layers each having on its inner face anumber of parallel ribs, the ribs of one layer crossing those of the other at an angle and being bonded to them. In a variant, there is an additional intermediate layer also having ribs on both its faces, these ribs crossing and being bonded to the inwardly projecting ribs of the outer layers. In yet another variant, there are two such intermediate layers on the same principle. The ribs of the outer layers are in general parallel within each layer, and may be straight on both outer layers, curved on both outer layers, or curved on one layer and straight on the other. The presence of ribs running in more than one direction gives the same stiffness against bending normally possessed by corrugated packaging material or the like, but in the present case stiffness in every direction.
