Patent GB-419893-A (GB)
Title: Improvements in the manufacture of films or foil
IPC: B29C48/20
Filed: 1933-07-26
Abstract: A patterned film or foil is obtained by applying a solution of cellulose acetate or similar material to a casting surface from a pouring vessel and supplying a second solution of cellulose acetate to the material emerging from that vessel.  The two solutions may be of different colours or shades of colour, or one may be uncoloured. The casting surface is preferably a rotary drum or endless band upon which the solvent is evaporated from the film material.  The patterning solution may be supplied from one or more auxiliary pouring vessels, the slots of which are divided in accordance with the pattern stripes desired.  The first solution exerts a tractional force on the stripes of the further solution and prevents <PICT:0419893/IV/1> <PICT:0419893/IV/2> the narrow apertures from becoming blocked.  The film may show ribbed effects if it is allowed to shrink during drying.  As shown in Fig. 1, two pourers 10, 11 are formed by the plates 12, 13, 14, and end plates 15, 28.  A doctor or stripper knife 18 rests on plate 12 and is adjusted by the screw 19. The plate 13 forming the rear wall of the main pourer 10 and the front wall of the patterning pourer 11 abuts at its lower edge against plate 14 and the matrix 21.  The matrix 21 has apertures 27, Fig. 2, in accordance with the desired patterning, and it may be adjustable on the plate 14.  Plate 13 is adjusted by screws 24 and together with plate 14 is pivotally mounted on a stay bolt 16.  The inclination of plate 14 is adjusted by the screw 22 with ball-joint 29.  In operation, the patterning solution passes into the solution, emerging from the pourer 10 on to the drum or band 17.
