摘要:
Apparatus for continuously cutting a web and removing trim strips therefrom, including a pair of circumferentially spaced knives supported on a cutting shaft, the shaft being rotationally mounted for cutting, in a cutting area, the web transverse to its direction of movement for forming trim strips, a cylinder mounted along the underside of the web for rotation about an axis which is generally perpendicular to the direction of the moving web, the cylinder having a hollow bore communicating with a low pressure source and an opening formed in the surface of the cylinder communicating with the bore for providing low pressure at the opening, the cylinder being rotated at a predetermined speed such that the opening is positioned in the cutting area immediately downstream of the knives each time a trim strip is cut from the web and the opening is rotated away from the cutting area immediately thereafter.
