ABSTRACT:
The invention relates to apparatus for cutting a series of spaced-apart continuous linear slits in a sheet of flexible plastics material, for example in the manufacture of an ajustable width blind. In one embodiment the apparatus includes a feed roller for feeding sheeting to be slit to a support means, a plurality of slitting blades movable in a direction transverse to the direction of travel of the sheeting and means for controlling the blades so that they cut to a depth less than the thickness of the material. In a second embodiment the blades are stationary and are adapted to cut in the direction of travel of the material. The blades may be mounted on leaf springs biased towards the material to be cut, means being provided for controlling the biasing force. Alternatively, a stop may be provided to control the depth of cut of the blades.
