Title:
ROTARY CUTTER
Document Type and Number:
Japanese Patent JPS61288994
Kind Code:
A
Abstract:
An improved rotary cutter for a web material is proposed. It has a pair of rolls adapted to rotate synchronously in opposite directions and an axially elongated knife secured to each roll to extend axially. A plurality of rolling bodies are arranged around each roll to bear the shock upon cutting. Different means for preventing the knives from hitting the rolling bodies are proposed. This arrangement prevents the rolls from warping due to shock upon cutting and allows the use of rolls having a smaller diameter.
