Patch applicator vacuum cylinder for web material |
摘要 |
An applicator for applying patches to a traveling web, such as in a bag forming machine, includes a vacuum cylinder with an outer perforated sleeve, an inner slotted sleeve and a stationary core with shaped pressure chambers for applying patches cut from a roll to the traveling web. Cutting blades are included in the perforate outer sleeve to sever patch material from a roll as the vacuum cylinder rotates. The outer perforate sleeve is replaceable with sleeves of different outside diameters to accommodate different patch locations.
