Thermoplastic polymer sheet material having a thickness greater than 7 mm. is made by extruding the polymer whilst hot through a slit die and passing the extrudate over cooling rolls such that the faces of the sheet are alternately cooled, and at at least one roll heating the face opposite that in contact with the roll. Two to five rolls may be utilized, their temperatures being adjusted to lie 10-50 C. below the temperature of the contacting extrudate. The rolls may have diameters within the range 20-60 cm. with generally a larger diameter roll being used for greater thickness extrudate. Heating may be effected by electrical means, gas burners or infra-red heaters, the latter being preferred, and it is also preferred that heating occur at the furthest downstream roll. The sheet may be drawn flat from this roll with or without use of support or guide rollers. Specific polymers mentioned are normal or low-pressure polyethylene, normal or isotactic polypropylene, P.V.C. and polystyrene. Four examples are given.

Abstract: 410,298. Dressing fish. BAADER, R., 33, Wakenitzmauer, Lubeck, Germany. March 15, 1933, No. 7852. [Class 28 (ii).] A machine for skinning fishes, particularly fish fillets previously prepared in a machine which leaves the fillets adhering to the backbone adjacent to the tail fin, comprises as shown in side elevation in Fig. 2, grippers 23, 231 which seize the skins of the fillets adjacent to the tail and then perform a combined motion of an oscillation about the pivots 2, 2<1> and a longitudinal motion parallel to the direction of movement of the fish which is moved by a grip 1. The skin is separated from the flesh by rapidly oscillating knives 48, 48<1> which effect scraping and beating movements perpendicular to their cutting edges. The fish is resiliently held against the knives 48, 48<1> by abutments 58, 581. The fish delivered from the filleting-machine is seized by the tail by the grip 1, and, in the position f is engaged by the grippers 23, 23<1>. At the position f<2>, two spaced pivoted cam-actuated knives 42 sever the adhering flesh from the tail end of the backbone, and at the position f<3>, a pivoted cam-actuated bifurcated knife 32 severs the skin at the tail end from the fillets. The backbone is then completely detached from the fillets and is subsequently discharged from the grip 1. The rocker arms 3, 31 carrying the grippers 23, 23<1> and the abutments 58, 581 are carried on a bell-crank lever, (not shown in Fig. 2), which is oscillated to produce the longitudinal movements of the grippers and abutments. At the initial fish-engaging position of the grippers 23, 231 (shown in fine lines in Fig. 2), the abutments are held out of contact with the fish by cams 63, 63<1> associated with the grippers. The rocking of the arms is effected by gear wheels 5, 6 driven by a wheel 7 which is oscillated by a cam-driven oscillating quadrant. The grippers are opened and closed by backward extensions 24, 241 engaging rotary cam plates which are actuated by the rocking of the arms 3, 31. The knives 48, 481 are carried on shafts 47, 47<1> which are oscillated by cranks and connecting rods. The skinned fillets fall upon endless discharge conveyers. Specification 392,668 is referred to.
