Abstract: In order to seal the corner joint of an elastoplastic tape placed as a spacer on a glass pane, a film strip is pressed with a first portion of its length against the first leg section of the spacer and the protruding portion of the film strip is wrapped around the corner and pressed against the second leg section. For the purpose of automating this process, the film strip is severed mechanically from an automatically supplied film tape and held via a transfer apparatus which thereafter presses the film strip with the first portion of its length against the first leg section. The portion of the film strip protruding freely over the corner is wrapped around the corner via a pressure carriage and pressed by tautening against the second leg section of the spacer.

Abstract: A slip-on corner protector for rectangular picture frames includes a flat cardboard pre-form which is bent into the shape of a hollow prism having right triangularly-shaped front and rear frame face cover panels joined at vertical and horizontal sides thereof by a vertical and horizontal rectangularly-shaped frame edge cover panel, respectively. Triangularly-shaped spring flaps bent inwardly from hypotenuse edges of the front and rear triangular panels are pressed against and thus grip a frame inserted between the front and rear triangular panels because of the elasticity of the cardboard pre-form. A machine and method for manufacturing corner protectors from a stack of pred-forms bends panels perpendicularly upwards from a pre-form by linear actuators, spays a hot melt adhesive blob onto an upright panel, and presses it against another upright panel to form an adhesive bond.

Abstract: The present invention is a process for performing a planarization treatment of pressure-sensitive adhesive (PSA). The process includes positioning a first substrate onto a support surface of a planarization tool. The process further includes placing at least one layer of PSA onto the first substrate. The process further includes positioning a second substrate onto the layer(s) of PSA. The process further includes applying a pressure to the second substrate via a flexible membrane, said pressure being applied in a generally uniform, unidirectional and localized manner. Further, the applied pressure flattens the PSA between the first substrate and the second substrate for promoting suitability of the PSA for use in rigid-to-rigid lamination processes.

Abstract: A method for manufacturing light emitting devices is provided. The method may reduce the inner pressure of a laminated image emitting device panel, thereby preventing failure of the panel. The method includes holding a first substrate with a lower chuck located in a vacuum chamber; holding a second substrate with an upper chuck located opposite the first chuck in the vacuum chamber; creating a high vacuum in the vacuum chamber; correcting positions of the first substrate and the second substrate; supplying gas having a temperature of about 50 to about 200° C. into the vacuum chamber; temporarily laminating the first substrate and the second substrate; venting the vacuum chamber; and bonding the first substrate and the second substrate. The panel is laminated after being filled with a heated gas and thus, when it is exposed to room temperature, the mobility of the gas decreases while reducing its initial inner pressure, thereby preventing panel failure.

Abstract: A fabrication process using an integrated form includes assembling at least two independent sections of composite laminate about a form, such that at least a portion of the sections overlap. A bonding agent is applied between the sections, at the overlap, and the form and laminate assembly are vacuum-bagged. The bag is sealed around a vent in the form, and about the laminate assembly. A vacuum is applied within the bag, to bond the sections, and the bagged assembly is autoclaved, to cure the bonded laminate sections. The vent allows equalization of autoclave pressures within and outside of the form, to prevent crushing or deformation of the form during cure. The form becomes an integral and permanent part of the final composite product.
