  • Patent number: 10361412
    Abstract: A method for forming a thin, board-like base material has a tensile transfer step and a forming step. In the tensile transfer step, the long, thin, board-like base material is transferred by pulling the thin, board-like base material in the transfer direction while holding both ends of the thin, board-like base material along the transfer direction and pulling the ends outward in the direction intersecting the transfer direction. In the forming step, predetermined forming operations are performed with respect to the thin, board-like base material.

  • Publication number: 20190193432
    Abstract: A print media feeding apparatus includes: a stacking part configured to stack the print media; a feeding roller which is movable to an abutting position at which the feeding roller contacts the print media stacked on the stacking part and to a separated position separated from the print media stacked on the stacking part and configured to feed a print medium by rotating at the abutting position; a separation member configured to separate the print media; and a return unit configured to perform a return operation of returning the print medium other than a top print medium which the feeding roller abuts. The feeding roller moves to the separated position, after feeding the print medium from the stacking part. The return unit performs the return operation upon the feeding roller moving to the separated position. After the return operation, the feeding roller stops at the abutting position.
