Abstract
Unwind assembly fixtures herein are useful in improved methods for application of polymeric film or laminate to at least a portion of a surface of an article. In an exemplary embodiment, such a method comprises: providing an unwind assembly fixture comprising an anti-static device; securing the roll of multi-layer sheet in the fixture; unwinding the multi-layer sheet from the roll; removing the release liner from the multi-layer sheet after it is unwound from the roll; capturing and re-rolling the removed release liner on another roll positioned in the fixture; and applying the polymeric film laminate to the surface of the article.
Claims24
An unwind assembly fixture useful for application of a polymeric film laminate to a surface of an article after removal of a release liner from a roll of multi-layer sheet comprising the polymeric film laminate, the fixture comprising:
- first and second longitudinally extending support bars;
- first and second film holders respectively disposed proximate upper ends of the first and second longitudinally extending support bars;
- first and second film holder/winder mechanisms respectively disposed proximate lower ends of the first and second longitudinally extending support bars, wherein the second film holder/winder mechanism facilitates unwind of the multi-layer sheet from a roll and the first film holder/winder mechanism facilitates capture and re-rolling of the release liner after its removal from the roll of multi-layer sheet;
- and
- an anti-static device positioned approximately parallel to the first and second longitudinally extending support bars and spaced apart from the second support bar on a side opposite the first support bar and proximate a point at which the release liner is removed from the roll of multi-layer sheet during dispensing of the polymeric film laminate for application to the surface of the article.
An unwind assembly fixture useful for application of polymeric film or laminate to a surface of an article, comprising:
- a film holder for mounting of a multi-layer sheet in roll form;
- and
- an anti-static device that extends across width of the multi-layer sheet or a portion thereof during unwind of the multi-layer sheet from the roll.
