Abstract
A two-shaft linear motion type winder for winding up a sheet material, e.g. a film is provided, which can eliminate the occurrence of any mechanical loss by simplification of a transission device, shorten the path distance of the film upon roll changing, prevent the neck-in and wrinkling of the film and reduce vastly the roll changing cycle. It comprises at least a pair of upper-stage winding frames having holders for an upper winding shaft, suspended from an upper main frame to be slidingly movable back and forth in a given area; and a pair of lower-stage winding frames having holders for a lower winding shaft, disposed on a lower main frame to face upwards so as to be slidingly movable longitudinally in a given area. The holders for the upper and lower winding shafts are capable of ascending and descending vertically; and each of the upper-stage and lower-stage winding frames, upon full winding, move the one winding shaft with a full roll from a winding position to a removal position of the roll while shifting the other winding shaft to the winding position thereby enabling the roll changing; each of the frames and holders being movable individually without mutual interference.
