    • A dispenser for coiled sheet material, such as paper towelling, having an improved transfer mechanism for transferring feed from a partially consumed roll of sheet material to a fresh or reserve roll. The sheet from the partially consumed roll is fed across an apron to a pair of cooperating feed rolls. The transfer mechanism comprises a sensing finger carried by a pivotable frame which rides on the sheet material being dispensed from the partly consumed roll. When the end of the sheet material moves past the finger, the finger being unsupported, will drop through an opening in the apron to thereby pivot the frame downwardly and cause a roller to move the free end of the sheet of the reserve roll into the nip between the feed rolls so that the sheet from the reserve roll will then be fed from the dispenser. A pivotable discharge plate is mounted at the discharge opening of the dispenser and can be pivoted between a controlled feed position and a free feed position. When in the controlled feed position, only predetermined lengths of the sheet can be dispensed, but when the plate is in the free-feed position, a continuous length of sheet can be dispensed.
    • 卷纸片材的分配器,例如纸巾,具有改进的转印机构,用于将来自部分消耗的片材材料的纸料转移到新鲜或备用卷轴上。 来自部分消耗的辊的片材穿过围裙被馈送到一对协作的进料辊。 传送机构包括由可摆动的框架承载的感测手指,该可转动的框架在从部分消耗的卷筒上分配的片材上滑动。 当片材的端部移动超过手指时,手指不支撑,将通过围裙中的开口落下,从而向下枢转框架,并使辊将储备辊片的自由端移动到夹持部 在进给辊之间,使得来自保留辊的片材然后将从分配器进给。 可枢转排放板安装在分配器的排出口处,并且可以在受控进给位置和自由进给位置之间枢转。 当处于受控进给位置时,只能预定长度的片材被分配,但是当板处于自由进给位置时,可以分配连续长度的片材。
