Apparatus for cutting and simultaneously dispensing a web of roll material comprising a carrier for a roll of material mounted in a casing and urged against a rotatable drum which is driven in rotation by manual traction applied to a free end of the material extending from the casing. A profiled pawl is supported at one of the ends of the drum and cooperates with a shock absorber and an elastic abutment to brake the drum at the end of one revolution and hold it in readiness for a subsequent pull on the material. An eccentric lever is secured at the other end of the drum and is engaged by a spring such that in a first portion of rotation of the drum, the spring absorbs energy and after a dead point, it releases its energy to drive the drum in rotation. The drum has a longitudinal slot and a cutting member is pivotably mounted in the slot and carries a follower which cooperates with a fixed cam such that the cutting member is retracted in the drum in a inoperative position and projects from the slot in the drum in the operative position to produce a cut across the entire width of the material while the latter is maintained in tension on both sides of the cutting member.
An apparatus for successively cutting and simultaneously distributing sections from a web of roll material, the apparatus having a casing, a carrier for a roll of material mounted in the casing, a rotatable drum in said casing, said carrier being urged towards said drum such that the roll of material is frictionally engaged with the drum to cause the drum to be driven in rotation by manual traction applied to a free end of the material extending from the casing, said drum having opposite ends, a profiled pawl supported at one of the ends of the drum, elastic means positioned to engage said pawl for braking the rotation of said drum and halting the drum after one revolution thereof, an eccentric lever mounted at the other end of said drum for rotation therewith, energy storage means engaging said lever for resisting rotation of the drum during an initial period of rotation thereof while storing energy and then driving the drum in rotation by the stored energy, and cutting means for cutting the material on said drum, an improvement wherein said drum is hollow, said cutting means comprising a cutting member pivotably mounted in said drum for movement between operative and inoperative positions, cam means for pivotably moving the cutting member to its operative position by the drive of the drum, said drum having a slot therein, said cutting member being retracted in said drum in said inoperative position and projecting from said slot in said operative position, said cutting member being displaced by said cam means under the drive of the drum along a trajectory in the same direction of rotation of the drum to reach said operative position and cut the material to free a section thereof for release under the manual traction in the course of rotation of the drum.
