The goal is to improve the performance of the cutting device. The device for cutting materials contains a movable knife 3, a roll holder 2, pulling rollers 9 and a double-arm lever 4. At one end of the lever the knife 3 is fixed, and the other is connected to the brake belt 5. When cutting using a braking mechanism, the material is tensioned roll holder and pull rollers. The device allows you to cut material without stopping it. This provides the necessary tension on the material in the cutting area. 1 il.

На чертеже изображено устройство дл резки рулонных материалов в исходном положении.The drawing shows a device for cutting roll materials in the initial position.

Устройство дл резки материала 1, подаваемого с рулона, закрепленного в рулонодержателе 2 с приводом (не показан), содержит подвижный нож 3, закрепленньй на одном конце двуплечего рычага 4, тормозную ленту 5, соединенную св зью 6 с другим концом двуплечего рычага 4, тормозной шкив 7, закрепленный на оси рулонодержа- тел 2, привод 8 ножа 3 и т нущие ролики 9 с приводом (не показан). Двуплечий рычаг 4 вращаетс вокругA device for cutting material 1 supplied from a roll secured in a roll holder 2 with a drive (not shown) contains a movable knife 3 fixed on one end of a double arm 4, a brake tape 5 connected by linking 6 with the other end of the double arm 4, a brake a pulley 7 fixed on the axis of the roll-holding body 2, a drive 8 of the knife 3, and t driven rollers 9 with a drive (not shown).

axes 10. The direction of the moving mother-25, for example, paper and cardboard, contained by the guides 11.

A device for cutting materials works as follows.

Material 1, for example paper, is continuously fed from a roll of holders SO 2 into the cutting zone along guide rails 11 by continuously rotating rollers 9, which ensure the movement of the material

The roll holder mounted in the frame, the braking mechanism, the sub knife and pulling rollers, characterized in that, in order to increase productivity, it is equipped with a double-arm lever, the braking mechanism is complete in the form of a pulley mounted on the axis of the roll holder, and the belt is covered by a pulley , one

The roll holder installed in the frame, the braking mechanism, the sub knife and pulling rollers, characterized in that, in order to increase productivity, it is equipped with a double-arm lever, the braking mechanism is executed in the form of a pulley mounted on the axis of the roll holder, and the belt braking pulley single

with

At the same time, the other arm of the lever 4, through the link 6, pulls the brake brake strip 5, presses it onto the brake pulley 7 and applies the braking torque to the axis of the roll holder 2 with material 1 at the time of cutting, which provides tension on the material 1 between roll holder 2 and t with the help of rollers 9, which contributes to high-quality cutting.

After the knife 3 is retracted to the initial position, the two shoulders lever 4, through coupling 6, retracts the brake band 5 from the brake pulley 7. This retards the braking torque from the axis of the roll holder 2 and the material 1 moves freely between the guides 11 to the pulleys 9. Then the cycle turns up.
