Abstract:
An apparatus for producing an easy-to-tear plastic film comprising a pattern roll rotatably supported by a pair of stationary frames, an anvil roll moving along a pair of movable frames, a first driving unit for rotating the movable frames, and second driving units each mounted to the movable frame to move the anvil roll up and down; high-hardness, fine particles projecting from a rolling surface of the pattern roll having such average height and maximum height as enabling the formation of unpenetrating fine pores in a plastic film; with the anvil roll inclined to the pattern roll in a horizontal plane by the operation of the first driving unit, large numbers of unpenetrating fine pores being formed transversely uniformly in the plastic film passing through a gap of both rolls.

Claim (Index 1):
An apparatus for producing an easy-to-tear plastic film randomly having large numbers of unpenetrating fine pores on an entire surface of a plastic film, comprising\n a first roll rotatably supported by a pair of laterally arranged stationary frames; a second roll movable up and down along a pair of laterally arranged movable frames, such that said second roll comes into contact with said first roll via a plastic film; a conveying mechanism for passing said plastic film through a gap between said first and second rolls; a first driving unit for rotating a pair of said movable frames; second driving units each mounted to each of said movable frames to move said second roll up and down; a third driving unit for rotating said first roll; and a fourth driving unit for rotating said second roll; one of said first and second rolls being a pattern roll randomly having large numbers of high-hardness, fine particles on its rolling surface, and the other being an anvil roll having a flat rolling surface; the high-hardness, fine particles projecting from a rolling surface of said pattern roll having such average height and maximum height as to enable the formation of unpenetrating fine pores having an average depth corresponding to 30-80% of the thickness of said plastic film and the maximum depth corresponding to 90% or less of the thickness of said plastic film, in said plastic film; and with the center axis of said second roll inclined to the center axis of said first roll in a horizontal plane by the operation of said first driving unit, said plastic film passing through a gap between said first and second rolls, thereby forming large numbers of unpenetrating fine pores transversely uniformly in said plastic film by said high-hardness, fine particles.
