摘要： An automatic drafting machine in which the paper is disposed on drive rollers and the paper is sandwiched by the drive rollers and pressure rollers in resilient contact with the drive rollers, and a writing implement is shiftably disposed in a right angle direction to the feeding direction of the paper along the horizontal surface of the paper, and guides for mounting the paper are disposed on both sides of the track along which the writing implement shifts, and an air blowing opening for supplying downward air pressure on the paper is disposed in the vicinity of the outer end portions of the guides in the feeding direction of the paper.

摘要： A paper feeding device for automatic drafting machine in which paper is fed in a predetermined direction by drive rollers and pressure rollers that are in resilient contact with the drive rollers. A writing implement is shiftably disposed in a right angle direction to the feeding direction of the paper, and the writing implement abuts on the paper. A predetermined pattern is drawn on the paper by mutual operations of the transfer of the writing implement and the transfer of the paper in the feeding direction. Underlay rollers are disposed in parallel to the transfer path immediately below the transfer path of the writing implement. The direction of drive and rotation of the underlay rollers is identical with that of the drive rollers, and a circumferential speed of the surfaces of the underlay rollers is set slightly higher than a circumferential speed of the drive rollers.
摘要翻译：一种用于自动牵伸机的送纸装置，其中通过与驱动辊弹性接触的驱动辊和压力辊沿预定方向进给纸。书写工具可移动地布置在与纸张的进给方向成直角的方向上，并且书写工具邻接纸张。通过书写工具的传送和纸张在馈送方向上的传送的相互操作，在纸张上画出预定的图案。底板辊平行于书写工具的传送路径正下方的传送路径设置。底盘滚轮的驱动方向和旋转方向与驱动辊的驱动方向相同，底盘的表面的圆周速度设定得比驱动辊的圆周速度略高。
