Abstract
A cutter employing two heated eccentrically mounted rollers adapted to coact with each other in order to sever a material by means of a crushing action is utilized in conjunction with a transport member to cut predetermined lengths of material from a continuous roll of said material. The cutting action of the heated rollers provides cut ends of the material which may be readily spliced together without the use of gum strips.
Claims13
An apparatus for cutting material, comprising:
- a. a first roller assembly having a curved surface adapted for eccentric rotation,
- b. a second roller assembly having a curved surface adapted for eccentric rotation wherein the curved surface of said first roller assembly may be positioned proximate to and in axial alignment with the curved surface of said second roller assembly in order to at least partially cut said material, and
- c. means for causing eccentric rotation of the curved surface of said first and second roller assemblies.
An apparatus for cutting a deformable material comprising:
- a. a first roller adapted to be rotated about an axis eccentric to the center of said roller,
- b. a second roller adapted to be rotated about an axis eccentric to the center of said roller and further having the axis of said second roller parallel to the axis of said first roller wherein the periphery of said first and second rollers may be placed in proximate relationship by rotating said first and second rollers in order to at least partially cut said material, and
- c. means for rotating said rollers.
In an apparatus for dispensing innerliner material from a continuous roll, the improvement comprising:
- a. means for cutting said innerliner material including at least one eccentrically mounted curved surface adapted to at least partially cut said material when eccentrically displaced whereby said cut edge of said innerliner material is tapered;
- and
- b. means for placing said innerliner material for cutting by said cutting means whereby a predetermined length of innerliner material may be cut.
A method for cutting a material using two substantially parallel eccentrically mounted heated rollers comprising the steps of:
- a. placing said material between said rollers,
- b. rotating said rollers to a position wherein said rollers are immediately adjacent to one another whereby said material is at least partially cut,
- c. rotating said rollers to a position wherein said rollers are sufficiently far enough apart to remove said material from between said rollers, and
- d. removing said deformable material from between said rollers.
