Abstract: Methods and apparatuses for forming a handling tab on a glass substrate are disclosed. The method may include conveying a glass substrate in a conveyance direction. An adhesive tape ribbon may be positioned adjacent to the first lateral edge of the glass substrate such that an adhesive surface of the adhesive tape ribbon is spaced apart from the first lateral edge of the glass substrate and the adhesive surface is substantially perpendicular to the first surface and the second surface. The adhesive tape ribbon may be folded such that at least a portion of the glass substrate is positioned between the adhesive surface of a first portion of the adhesive tape ribbon and the adhesive surface of a second portion of the adhesive tape ribbon, and a third portion of the adhesive tape ribbon forms a handling tab extending beyond the first lateral edge of the glass substrate.

Abstract: An ultrasonic apparatus and method for forming individual pillowed chips of light lock material are provided. An ultrasonic horn and ultrasonic anvil are used to form pillows in a composite web of light lock material. The pillowed web material is then notched and cut to produce individual chips of light lock material. Each individual chip has one pillowed edge and one non-pillowed, notched edge. The pillowing and notching facilitate placement of the individual chips of light lock material into a film cartridge.

Abstract: A spool (10) including a core (12) and end disks (18, 24) retained by tabs (16, 22) is assembled by sliding each end disk over the core into proximity with its associated tabs, contacting the end disk with at least a single point tool (106; 228-252) and rotating the tool to snap the disks past the tabs one by one. A transducer assembly (142-160) measures axial force applied to the core to detect successful installation of each end disk.

Abstract: An ultrasonic apparatus and method for placing individual pillowed chips of light lock material in a cartridge are provided. A vacuum plate mounted on a pivotable arm picks up a chip and releases it into a cartridge. The cartridge has a recessed area into which the pillowed edge of the chip fits. Once positioned with the cartridge, utilizing a tuck plate, the chip is sealed in place using an ultrasonic horn.

Abstract: Webs (12, 14) to be spliced are provided with end edges (24, 26) which are positioned with an overlap (38), covered by a metal buffer strip (60) and joined by application of ultrasonic energy (54, 62, 64).

Abstract: A cut end (18) of a web (14) is held by a vacuum shuttle head (105, 106, 108, 136, 138) and a central vacuum finger (114-124) holds a central tongue (22) of the web during insertion into a preassembled cartridge (50, 52, 26). During winding the cartridge is rotated (174-184) to avoid scraping the web on the cartridge.
