FIELD: process engineering.SUBSTANCE: invention relates to cutting the material off the web. This method is used in production of impregnating article and includes the steps that follow. Web is fed and retained relative to bearing surface. Material to be cut off is retained at bearing surface lifted from said bearing surface at the feed of said retained material. Material lifted from the web is cut off by blade spaced from said bearing surface. Proposed device comprises: Displacing bearing surface for web feed in machine direction, web material lifting element, blade to penetrate through lifted material retained in lifted position. Note also that said blade should be spaced from bearing surface to allow cutting said material off the web.EFFECT: perfected design.26 cl, 12 dwg |
