Abstract
Strips cut by an edge trimmer are engaged by rollers pulling the strips through a pipe and permitting the strips to hang down and descent through a funnel towards a horizontally operating cutter comprised of an annular blade across which passes an excentrically rotating blade, to cut the strips into small pieces. The rotating portion of the cutter may include two blades, and the stationary part may have plural annular blades arranged around the axis of the rotation of the blades; different strips such as from different trimmers are fed to the annular blades, surrounded by separate funnels.
Claims22
Apparatus for cutting strips cut from edges of webs upon edge trimming of the webs, comprising:
- means for grippingly engaging the cut strips and advancing them at the rate of strip cutting pursuant to the edge trimming, being he rate at which the strips arrive, said means for gripping, progressively releasing the cut strips so that the strips bend downwards freely under the force of gravity;
- stationary means defining a horizontally oriented opening towards which the strip bends and descends;
- a curved cutting edge mounted in the opening;
- a cutting blade mounted for rotation about a vertical axis and for periodically passing the cutting edge for cutting the strips into small cuttings;
- and
- means for driving the cutting blade.
Apparatus for cutting strips into small pieces, the strips having been cut from edges of several different webs by means of several trimmers, comprising:
- a stationary, horizontally positioned plate having a plurality of openings arranged around a center;
- a plurality of curved cutting edges, respectively in the openings, and positioned in a common plane;
- at least one cutting blade mounted for rotation on a vertical axis through said center, the blade having an edge moving in said plane;
- plural means disposed above said plate for grippingly engaging said strips and moving them into points above said openings and in vertical alignment with said openings, at least one strip per opening, the means for gripping, progressively releasing them to permit them to freely descend by gravity towards the respective opening and to be cut upon trasversal of the opening.
