Abstract

1427467 Cutting apparatus DE MAN ISOLATIEBV 25 Jan 1974 [25 Jan 1973] 03494/74 Heading B4B A device for cutting articles, e.g. pipe insulating sleeves 13, 14, from blocks 6 of synthetic foam material comprises one or more knives 1, 2, 3 arranged to be either stationary and the material pushed by means 4 against the knives to effect the cut, or vice versa, and guide means to keep the block in the correct position transversely with respect to the cutting direction. As shown in Fig. 1, three sets of knives 1, 2, 3 are secured to a frame made up from e.g. angle-iron so that the corners of the block 6 are located by the angle iron sections as the block is pushed through the frame against the knives; the pushing means 4 may be coupled to the ram of an hydraulic cylinder. The pusher 4 is provided with a further knife 10 which, during the pushing stroke severs a new block 11 from a web 8 of the material. As shown in Fig. 1, the cutting edges of each set of knives are arranged in staggered relation to facilitate the severing; alternatively they may be arranged in the same plane if desired. In modifications, the blades may be vibrated ultrasonically during cutting, the material can be held stationary and the knife frame moved or the frame and material can be moved together in opposite directions. The device may be operated automatically by suitable control means.
