WEB PROCESSING WITH SEMI-ROTARY ACCUMULATOR

摘要

Various apparatus embodiments include first, second, third and fourth idler shafts, and further include a first movable idler shaft having a first movable axis that is movable between a first axis position and a second axis position, and a second movable idler shaft having a second movable axis that is movable between a third axis position and fourth axis position. At least one linkage connects the first movable idler shaft to the second movable idler shaft. A motor linkage connects the at least one linkage to at least one motor for providing simultaneous movement of the first and second movable idler shafts.

1. An apparatus, comprising:
a first idler shaft, a second idler shaft, a third idler shaft, and a fourth idler shaft; a first movable idler shaft having a first movable axis that is movable between a first axis position and a second axis position, and a second movable idler shaft having a second movable axis that is movable between a third axis position and fourth axis position; at least one linkage connecting the first movable idler shaft to the second movable idler shaft; and a motor linkage configured to connect the at least one linkage to at least one motor for providing simultaneous movement of the first and second movable idler shafts, wherein simultaneous movement of the first movable idler shaft toward the first axis position and the second movable idler shaft toward the third axis position increases a length of the first web path between the first and second idler shafts and decreases a length of the second web path between the third and fourth idler shafts, and simultaneously movement of the first movable idler shaft toward the second axis position and the second movable idler shaft toward the fourth axis position decreases the length of the first web path between the first and second idler shafts and increases the length of the second web path between the third and fourth idler shafts.
