An image forming system includes an image forming apparatus including an image forming unit and a first control unit which controls the image forming unit, a varnish application apparatus provided downstream in a sheet conveyance direction with respect to the image forming apparatus and including a varnish application unit which applies varnish to a sheet and a second control unit which controls the varnish application unit, and a sheet conveyance apparatus provided between the image forming apparatus and the varnish application apparatus in the sheet conveyance direction and including a receiving roller which receives a sheet discharged from the image forming apparatus, a processing unit which performs predetermined processing on a sheet present in the sheet conveyance apparatus, and a third control unit which controls the processing unit, wherein the first control unit is capable of communicating with the second control unit and the third control unit.

There is disclosed a method of manufacturing an adhesive tape (32), comprising: printing a print pattern (14) including at least one printed datum (15) onto a web; applying onto the web a plurality of transversely spaced adhesive stripes (16) using an adhesive stripe applicator; and controlling adhesive stripe application such that the adhesive stripes (16) are applied in register with the print pattern (14) by monitoring the transverse position of at least a part of at least one printed datum (15) and adjusting the relative transverse position between the adhesive stripe applicator and the web in response thereto. The method also comprises a tape slitting operation in which, using a tape slitting head (92), the web is slit into a plurality of adhesive tapes (32) which each have an adhesive stripe (16); and controlling the tape slitting such that the web is slit in register with the print pattern (14) by monitoring the transverse position of at least a part of at least one printed datum (15) and adjusting the relative transverse position between the tape slitting head (92) and the web in response thereto.

Methods of processing a glass substrate comprise the step of obtaining a glass substrate and a tab removably attached to a portion of the glass substrate. The position of the glass substrate is manipulated with the engagement portion and the tab is removed from the portion of the glass substrate by releasing a mounting portion of the tab from the portion of the glass substrate without damaging the glass substrate. In further examples, methods include the steps of removably attaching first and second tabs to respective first and second surfaces of a glass substrate and coiling the glass substrate on a storage roll wherein the first tab adheres to the second tab. In further examples, a glass apparatus comprises a glass substrate and a removable tab including a mounting portion attached to a portion of the glass substrate with a first peel force of less than about 10 N/cm.

There is disclosed a method of manufacturing an adhesive tape (32), comprising a tape slitting operation in which, using a tape slitting head (92), a web (30) having a plurality of transversely spaced adhesive stripes (169) is slit into a plurality of adhesive tapes (32) which each have an adhesive stripe (16). The tape slitting is controlled such that the web (30) is slit in register with the adhesive stripes (16) by monitoring the transverse position of at least a part of at least one adhesive stripe (16) and adjusting the relative transverse position between the tape slitting head (92) and the web (30) in response thereto. There is also disclosed apparatus for manufacturing an adhesive tape (32).
