A system and method for a triple saw system that may utilize a removable circular saw in a plurality of different configurations while still allowing the user may use removable circular saw remotely by removing it from the bench whereby the removable circular saw may have a bottom plate for use in connecting to the bench saw or to the miter saw.

A machine produces twisted paper for loose file packaging. The machine includes at least one auger to reduce a dimension, such as diameter, of paper as it is pulled from a roll. The material moves past the auger into a twisting assembly wherein the paper is twisted or rotated about a longitudinal axis of the machine inside a pipe or tube. The pipe or tube includes a cutout or interruption in the sidewall within which a wheel resides. The wheel grasps and advances the paper through the twisting assembly as it rotates. As the paper leaves the twisting assembly it is pulled or otherwise fed through an exist region and is cut into segments of small twisted pieces of paper. The twisted segments of paper are of suitable size for use as loose fill packaging.

A cutting unit includes a stationary frame, a cutting drum, and an anvil drum. The cutting drum and the anvil drum are arranged one over the other for cutting web material fed therebetween. The upper drum is centerd on a rotatable arbour and rotatably supported in the stationary frame. The lower drum is rotatable and movable towards and away from the upper drum. A rotatable carrier, movable towards and away from the upper drum, includes at least two contact rollers. The lower drum is shaftless and rests on the contact rollers. At least one contact roller is situated on either side of a central vertical plane of the lower drum for providing support of the lower drum by the contact rollers only. A pressing device moves the carrier and the lower drum towards and against the upper drum for providing cutting pressure between the upper drum and the lower drum.
