Abstract

Изобретение относитс к обработке бумаги и может быть использовано в строительных работах при резке обоев. Цель изобретени - снижение потребл емой энергии и улучшение условий эксплуатации. При включении колодки 8 нагревател пружина 2, выполненна из материала с термической пам тью, принимает пр молинейную форму. Подвижный нож 3, выполненный в виде пластинчатой иглы, режет бумагу. При периодическом изгибе и выпр млении пружина 2 перемещает св занную с ней штангу 1, к которой в нижнем конце прикреплен нож 3. Во врем работы устройство перемещаетс относительно бумаги по линии резани с помощью указател таким образом, чтобы бумага скользила по поверхности опорного башмака 6. При этом пластинчата игла, вход в окно опорного башмака 6, производит узкий продольный разрез вдоль линии резани . 1 з.п. ф-лы, 8 ил.The invention relates to the processing of paper and can be used in construction work when cutting wallpaper. The purpose of the invention is to reduce energy consumption and improve operating conditions. When the heater block 8 is turned on, the spring 2, made of a material with thermal memory, takes a linear form. The movable knife 3, made in the form of a plate needle, cuts the paper. During periodic bending and straightening, the spring 2 moves the rod 1 connected to it, to which the knife 3 is attached to the lower end. During operation, the device moves relative to the paper along the cutting line using the pointer so that the paper slides along the surface of the support shoe 6. In this case, the plunger needle, the entrance to the window of the support shoe 6, makes a narrow longitudinal section along the cutting line. 1 hp f-ly, 8 ill.
