Vacuum roller and its manufacturing method

FIELD: machine building.

SUBSTANCE: invention relates to the vacuum rollers to held, to transfer, to stow or to execute other operations with flexible materials. The vacuum roller contains internal cylinder, in which an internal chamber is made, for vacuum application it is connected with the vacuum course; external cylinder installed with possibility of rotation around the internal cylinder, and in which multiple holes are made, and actuator configured with the possibility to move the internal cylinder between the first and second positions. At that the vacuum roller has the first vacuum profile with the internal cylinder in the first position, and second vacuum profile with the internal cylinder in the second position.

EFFECT: roller is suitable for material handling at high linear speeds.

FIELD: printing industry.

SUBSTANCE: invention relates to folders with adjustable folding mechanisms. Proposed folder contains rotating folding-blade cylinder for shifting signature to be folder and at least one folding blade which can rotate inside folding-blade cylinder around first axle. Said axle in its turn, is secured on carrier rotating around axle. Carrier, in process of rotation can move out of folding blade cylinder. Carrier and folding blade cylinder are phase-regulated relative to each other by differential drive.

EFFECT: possibility of use of standard drives whose overall dimensions do not depend on phase shift implemented by such drives.

SUBSTANCE: device for folding of products contains the transporting component and the folding assembly. The transporting component is implemented with a possibility to hold on itself the first and second parts of the product and to release the first part of the product while keeping its second part. The transporting component is configured with a possibility of transportation of the product at the transportation speed. The folding assembly is located near the transporting component. The folding assembly is implemented with a possibility to accept the first part of the product from the transporting component and move slower in comparison with the transporting component, holding on itself the first part. At implementation of the folding method the product is brought to the folding assembly by means of the transporting component. The first part of the product is transferred to the folding assembly. The first part is moved at the speed, smaller, than the speed of motion of the second part. The first part is transferred to the transporting component with providing of folding.

EFFECT: possibility of product folding along the folding axis and making the first part of the product to contact with the second part for imposing of the first part on the second part.

SUBSTANCE: paper material is wound on the blank corresponding to the shape of the product, layer by layer coated with the adhesive, pressed, dried, the preform is impregnated with a vegetable oil, dried, cut into pieces corresponding to the dimensions of the product, and the product surface is handled. New features are layer-by-layer gluing the paper material, carried out with flour paste made from wheat flour with a mass fraction of wet gluten of not less than 28% and water in the ratio of 1:3.5. Sides of the wound paper material glued on the blank of a rectangular cross section is subjected to compression under a pressure of 490*104 PA for 10-15 min, and before drying the preform with a moisture content of 65-70% is removed from the blanks, impregnated at a temperature of 75-80C for 90-130 min with linseed oil with the addition of up to 3% by volume isopropyl alcohol with the further drying of the preform by heating to constant weight, in the mode - 6 days not less than 60C with a subsequent increase in temperature by 10C, bringing the temperature up to 110C.

EFFECT: shortening the duration of the technological process by accelerating the impregnation of the preform while maintaining the shape while increasing the strength of papier-mache products.
