  • FIG. 2 is a right side elevation of FIG. 1;
  • FIG. 3 is a section along the lines III-III of FIG. 1;
  • FIG. 4 is a section along the lines IV-IV of FIG. 1;
  • FIG. 5 is a perspective view of the lever handle and its fittings.
  • the apparatus of the present invention comprises a frame 1 formed on a side wall 2 and a bracket 30.
  • a projecting shaft 4 is provided, on which a free drum 5 is mounted and a roll of adhesive tape T is set on the drum 5.
  • a bolt and nut 6 fastens the side-wall 2 to the base 3.
  • a projecting shaft or means 7 is similarly provided, on which a free ratchet-disengaging member 9,
  • the angle portion 8 covers a part of the ratchet wheel 11.
  • a projecting shaft 15 is mounted on the frame 1 and a free guide-roll 16 is mounted on the shaft 15.
  • a carrier band comprising a plurality of endless belts stretches between the guide-roll 16 and the delivery roll 13 in peripheral grooves thereon connecting the rolls, the delivery roll being a principal roll and the guide roll being a subordinate roll.
  • a lever handle 18 is fixed with a bolt and nut 19 to the shaft 7.
  • the lever handle constitutes an integral body, as shown in FIG. 5, comprising a stop 20, a shaft-hole 21, a cover plate 22 and a handle grip 23.
  • a movable cutter 24 and a ratchet pawl 25 are provided, which are supported by shafts 26 and 27, respectively, and springs 28 and 29 are provided so that the movable cutter 24 and the ratchet pawl 25 may turn in the direction of the arrows.
  • the movable cutter 24 cooperates with a fixed cutter blade 35 which is fixed to a bracket 30 projecting from the frame 1, and cuts the tape, as will be explained.
  • a fixed cutter blade 35 which is fixed to a bracket 30 projecting from the frame 1, and cuts the tape, as will be explained.
  • a coil spring 36 is tensioned between the frame 1 and the lever handle 18, one end 37 thereof being fixed to the frame 1 and the other end 38 to the lever handle 18, so as to turn the lever handle always counterclockwise, biasing the operating lever into the rest position.
  • brackets 39 and 39' project from the frame 1, and a screw rod 41 fitted with a nut 40 is supported by the brackets.
  • the nut 40 can be driven up and down by turning the knob 42.
  • a movable cover 46 and a fixed cover 47 are installed on the left and right side of the apparatus as shown in FIG. 2 and FIG. 3.
  • the tape-cutter of the present invention having the above described structure is operated in the following manner:
  • One end of the adhesive tape T which is set on the drum 5 is pulled out and led via an intermediate roll 43 to the delivery roll 13.
  • the adhesive surface adheres to the periphery 44 of the delivery roll 13.
  • the tape-delivery roll turns clockwise and a predetermined definite length of the tape is delivered through outlet 45.
  • the lever handle 18 is pulled upwardly by the coil spring 36, and simultaneously the ratchet pawl 25 turns idlingly over the ratchet wheel 11, moving in the direction opposite to the preceding revolution, and the tape-delivery roll 13 remains stationary.
  • the tape is then cut by the cooperation of the movable cutter 24 and the fixed cutter 31.
  • the length of the tape to be delivered by one motion of the lever can be adjusted by driving the nut 40 up or down by turning knob 42.
  • an apparatus for cutting tape may have a structure where the lever handle is provided on the same shaft as the delivery roll, and the delivery roll is turned by means of the pawl and the ratchet wheel when the lever handle is pushed downwardly, thereby delivering the tape, which tape is cut by the movable cutter during the return pivoting of the lever handle.
  • a tape cutting apparatus has the characteristic that the delivery and cutting of the tape is performed by one movement, in a very simple structure.
  • An apparatus for cutting adhesive tape to a definite length comprising a frame,
  • said frame adapted to rotatably secure a roll of tape
