    • A yarn storing and feeding device having a stationary storage drum onto which an intermediate yarn store is wound by a winding-on device, and from which the yarn is withdrawn through a gap around the withdrawal end of the storage drum. At least one yarn stopping device is associated with the gap for controlling the withdrawal of yarn. The stopping device includes a stopping element arranged radially inwardly with respect to the gap, and movable radially outwardly to extend across the gap in response to a magnetic actuator located radially outwardly with respect to the gap.
    • 一种纱线存储和进给装置,具有一个固定的储存滚筒,一个中间纱线储存器被一个缠绕装置缠绕在该固定的储存滚筒上,纱线通过围绕储存滚筒的退出端的间隙从该纱线上取出。 至少一个纱线停止装置与用于控制纱线抽出的间隙相关联。 止动装置包括相对于间隙径向向内布置的止动元件,并且响应于位于相对于该间隙径向向外定位的磁性致动器,可径向向外移动以延伸穿过间隙。

    • A yarn storing, feeding and measuring device, particularly for jet looms, has a stationary drum onto which an intermediate yarn store is wound by a winding-on device and from which the yarn is withdrawn, yarn sensing means detecting the withdrawal of the yarn from the drum by generating pulse signals indicating that the yarn passes a detection area of the yarn sensing means, a plurality of yarn stopping devices arranged at angular intervals around the storage drum and a control device adjustable to desired yarn lengths to be withdrawn, said control device being responsive to said pulse signals such that an actuating signal is transmitted to a selected yarn stopping device whose angular position corresponds to the position of the yarn when said desired yarn length has been withdrawn. The yarn sensing means consists of yarn sensors, the number thereof being lower than and independent from the number of yarn stopping devices, and said control device comprises storing means for storing information regarding the yarn stopping device actuated at the end of the previous yarn withdrawal cycle and calculating means for determining one yarn stopping device to be actuated next among the plurality of yarn stopping devices on the basis of input information for the calculating means representing said desired yarn length and on the basis of said stored information.

    • PROBLEM TO BE SOLVED: To correct the conveyance amount of a sheet by reducing a control load and suppressing the shift of correction timing, even when the variation in the conveyance amount of the sheet in each phase of a conveying roller is small.
      SOLUTION: A sheet conveying device includes: a sheet feed roller 37 which conveys the sheet S from the upstream side to the downstream side in a conveying direction by a first drive roller 40; a sheet discharge roller; a PF motor 25 which drives the sheet feed roller 37 and the sheet discharge roller; a rotary encoder 49 which detects the original phase point (zero degree) and rotational phase of the first drive roller 40 rotated according to the drive of the PF motor 25; and a control section which stores a correction phase for correcting the conveyance amount of the sheet S conveyed according to the rotation of the first drive roller 40, can selectively execute the correction control of one pulse in the rotational operation of the first drive roller 40 and controls the presence/absence of the execution of the correction control, based on the rotational phase in the rotational operation of the first drive roller 40.
