Title: Wet treatment of optically critical films - using roll nips for stripping and washing treatments to eliminate surface contamination
Inventor: BAUM SIDNEY J
IPC: B29D7/00
Filed: 1973-12-14
Abstract: Thermoplastic film emerging continuously from a liq. bath is led through a roll nip to prevent entrained liq. being carried on by the film surface. Above the nip the film surface is sprayed to neutralise any residual liq. The spray drainings are trapped by the top of the roll nip and flow laterally to spill from the ends of the roll nip. An ancillary roll nip half submerged in the bath may be used for preliminary throttling of the entrained liqs. Pref. the film residence time in the bath is varied by tracking the guide system for the incoming film to vary the submerged length. For bath treatments producing a colour or tint effect, the submerged length may be adjusted automatically in response to an optical sensor monitoring the film appearance at a later stage. The process is suitable for treating longitudinally oriented PVA with colourants at throughputs of 3.63-9.00 m/min. for mfr. of shaded transparent polarising films and it prevents irregular reaction of the non-homogeneous surface with stagnant residual reagent, hence non uniform or opacity effects.
