Title:
CUTTING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2012/111268
Kind Code:
A1
Abstract:
Provided is a cutting apparatus (1), which can prevent a sheet material (10) from moving and being damaged even if a fixed blade (43) receives a resistive force from the sheet material, and which can prevent the fixed blade from being damaged.
A cutter unit (4) of a cutting apparatus is configured of a pair of carriages (5) that travel along rails in the longitudinal direction of a cutting table (2), and a cutter head (7), which travels along a rail provided on a beam member (6) between the carriages. The cutter head has a rotating blade (29) and a fixed blade that is pressed to the blade edge of the rotating blade. The fixed blade is held by means of a fixed blade holder (42), which is pivotally supported to the leading edge portion of a blade spring (40) such that the blade holder can swing, and the fixed blade is held at a cutting position by attracting the fixed blade holder using a permanent magnet (44). When the fixed blade receives an excessive resistive force from a fabric (10), the fixed blade inverts and retracts in the direction opposite to the drive direction of the cutter head.
