ABSTRACT:
A method and apparatus is described for use in combination with a machine for corrugating a continuous strip of flat sheet material which prepares the sheet material for separation into sections after it has been corrugated. A platform is located upstream of the corrugating machine. The platform is intermittently advanced in the direction of travel and at the speed of the sheet material so that the platform is stationary relative to the sheet material. A scoring device is located on the platform. The scoring device moves across the width of the sheet material as the platform moves with the sheet material to form a spanwise weak point in the material. After the material passes through the corrugating machine, it can readily be separated into sections at the weak points formed in the material by the scoring device. Depth of scoring can be varied also so that substantial/total separation can also occur within the corrugator though it would not separate the flat strip before it entered the corrugator.
