Abstract: A coating device for coating a coating solution on a web has a roller and a weir which partially constructs a solution store space. In the solution store space the coating solution is stored. When the web sequentially moves in a direction, the roller rotates and the solution in the solution store space is supplied on the web. Thereby a part of the solution overflows the weir such that another part of the solution may remain on the web to have a constant width in a widthwise direction of the web. A drying device has plural drying zones in which the web is fed after the coating of the coating solution. One of the drying zones is neighbored to the coating device. A top of the plural drying zones is constructed of a blow regulation member so as to confront to the solution on the web. The blow regulation member has holes through which is exhausted a gas evaporated from the layer of the solution on the web.

Abstract: A method of winding a polymer film web around a cylindrical core, where the core is heated by blowing hot-air against the core prior to winding the polymer film web, and the polymer film web is wound around the heated core while blowing hot-air against the polymer film web. In another embodiment of the winding method, the polymer film is wound while knurled along both edge parts in the width direction of the film to form knurls so as to gradually decrease in the thickness thereof from one end of the film that contacts with the core toward the other end of the film. Furthermore, a heat treating method for annealing a film roll and a heat treating apparatus therefor are disclosed, which method comprises the steps of surrounding the film roll with heat insulating panels and blowing hot-air against the film roll in the direction along the core axis while rotating the core intermittently or continuously at a rotary speed of from 0.04 to 4 revolutions per hour.

Abstract: In a method in which a thin-film support is continuously led into a vacuum chamber from the atmospheric air, subjected to surface treatment and led-out to the atmospheric air again, a pneumatical cutoff portion of a leading-in and leading-out section is constituted by seal roller sets each of which is formed by aligned pairs of leading-in rollers and leading-out rollers which are close to each other through slight distances, and the support is led-in and led-out while lapped at an angle of from 30 to 150 degrees around the pair of rollers nearest to the atmospheric air of the seal roller sets.

Abstract: A web holding unit is provided just in front of a cutting and splicing unit. The holding unit is comprised mainly of multiple pass rollers, a pass roller motor, a vacuum pump, and an up/down cylinder. As the unwinding of an old web comes to an end, a rod of the up/down cylinder extends, and the pass rollers of the holding unit abut against the old web. The pass roller rotates at lower speed than web transport speed, and during the transport, the old web is drawn onto the pass rollers by sucking of the pump. The old web is transported to the cutting and splicing unit with a position thereof being regulated by the holding means.

Abstract: A process for preparing a continuous optical compensatory sheet has the continuous steps of: coating a liquid of a resin for forming an orientation layer in a solvent on a surface of a moving continuous transparent film; drying the coated layer to form a transparent resin layer; subjecting the transparent resin layer to rubbing treatment to give an orientation layer; coating a coating liquid of a discotic compound in a solvent on the orientation layer to form a coated layer; drying the coated layer; heating the coated layer to form a discotic nematic phase, whereby a layer of discotic compound is formed; and winding up the transparent film.

Abstract: Knurling is applied to both side edge portions of a high-molecular film and then the film is wound up. A packing agent is applied to the knurled portions to enclose air at the time of winding in spaces between wound film layers and the film is put into an annealing isothermal chamber while contact between the wound film layers is prevented by the air. Preferably, the high-molecular film is made to pass through a heating zone just before the winding so that the high-molecular film after heated is wound up. More preferably, the winding core used for winding is a hollow porous winding core and high-temperature pressurized air is blown out onto the film through the hollow porous cylindrical surface.
