Abstract: The present invention relates to a polarization plate to a surface of a liquid crystal cell in a manufacturing process of a liquid crystal panel, where a rotary table is disposed with loading domains for the liquid crystal cell, with each domain sequentially moving to carry-in, cleaning, gluing and carry-out stations.The cleaning mechanism serves to cause an elastic plate to be pushed to the surface of the liquid crystal cell, thereby removing foreign objects.The gluing mechanism serves to cut the polarization plate on the carrier tape to a predetermined length, to thereby allow the same to be a polarization plate chip, which is in turn absorbed and supported by the glue head. The polarization chip is now torn apart from the carrier tape to thereby be glued to the surface of the liquid crystal cell.By this, process of picking up the polariation plate can be shortened and the position of the polarization plate can be determined in a state of the polarization plate being absorbed and supported by the glue head.

Abstract: A method of recycling an image-deposited recording material having a surface portion which swells in contact with water and bears thereon deposited images containing an image-constituting material, include the steps of: (a) applying a water-containing image removal promoting liquid to the image-deposited surface portion of the recording material, (b) bringing an image release member into contact with the image-deposited surface portion of the recording material to transfer the images to the image release member to remove the images from the image-deposited recording material, and (c) applying heat to the image-deposited recording material at least after the step (a), with substantially retaining the water component of the image removal promoting liquid in the image-deposited surface portion.

Abstract: A method and apparatus for joining plastic profile members together, particularly to form picture frames. The profile members are held in place by fixture members against a locator member. The locator member is withdrawn and a heated blade positioned between the ends of the profile members. The profile members are moved against the thin blade and the end surfaces are heated to an elevated temperature. The blade is removed and the ends are welded together. During a cooling period, the retracted blade can be cleaned as desired by a blade cleaning mechanism. After the joined profiles are removed, the members are returned to positions to begin another cycle.

The machine also has an improved glue reservoir system wherein glue is provided in sealed containers to be punctured at the time of loading the glue to the reservoir. Optional features are a forms compactor to keep glued forms together until glue sets, and a rotator/perforator for rotating forms at high speed to perforate lines at a right angle to previously perforated lines.

Abstract: A method and apparatus for fabricating resin mats having a plurality of mat layers is provided. Multiple mat sheets are conveyed between two spaced rollers while being impregnated with resin contained in at least one reservoir formed between the rollers and sheets. A resin feeding system supplies resin to a location between the sheets which substantially corresponds to the longitudinal centerlines of the sheets to ensure adequate impregnation of the mat layers while minimizing any residual resin from adhering to the rollers. Dam members are also positioned between the rollers at the longitudinal sides of the sheets to aid in forming the reservoir(s) and also to maintain an appropriate spacing between the rollers. The roller spacing is configured to permit a predetermined degree of slippage between the rollers and the mat layers.

Abstract: Apparatus for and method of restoring a damaged area of a coating on a drum body includes a treatment station with a coating-removal unit which initially mechanically frees the damaged area from remaining coating. After cleaning the freed damaged area, a patch is inserted and united with neighboring coating material through hot vulcanization or hot pressing for bonding to the drum body, with the patch having a material composition corresponding to the coating material. Finally after curing, the thus-restored area is surface finished to match the restored coating to the dimension and surface finish of the remaining coating of the drum body.

Abstract: A clog prevention device is disclosed for use with a label printing and applying machine. The clog prevention device includes a pair of juxtaposed label guide walls which extend longitudinally up from and at both sides of the printing platen.
