<p>A stock feeder feeds web stock from one of two web stock reservoirs and, upon sensing the depletion of the one reservoir, switches over to feeding from the second reservoir. The two reservoirs feed to a common point along two merging guide surfaces. The feeder allows for uninterrupted feeding. In an alternate embodiment, the arrangement permits the selective feeding from two reservoirs where each reservoir contains distinguishable stock in order to allow for desired sequences of distinguishable stock.</p> |
