    摘要： 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 an 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.
