Ledge (11) comprises front groove (15); element (13) of longitudinal cutting is located between transverse plate (10) and frontal groove (15). There is retaining element (4) rigidly coupled with support surface (3). Retaining element (4) is inserted into front groove (15). Invention also relates to preparation of food products and device for preparation of food products.EFFECT: technical result is increased strength of product while maintaining ease of its production.15 cl, 4 dwg

achine for cutting plastic bar // 2581434
FIELD: construction.SUBSTANCE: invention relates to the industry of construction materials, to devices for measuring cutting of continuously moving plastic bar into billets of bricks or other ceramic articles. Disclosed cutting machine for plastic timber comprises a housing, a support table for timber, a body with a vertical cutting string and a crank-and-rocker mechanism for moving body. Crank mechanism is connected to a rotary drive, controlled by signals of beam speed meter. Rocker arm is fixed on a support table capable of swinging in a plane parallel thereto. Connecting rod connecting crank and rocker arm is designed as a spatial figure, having at least one connection from remote nodes connecting rod with a yoke and crank point made in a plane parallel to plane of supporting table, moving along a path in form of figure eight. At said point, connecting rod is attached to body with cutting string so that centre of figure eight, described cutting string, falls on middle beam, edges are outside its scope, and axis is perpendicular to beam.EFFECT: invention is aimed at designing a simple, light-weight and reliable drive for moving cutting string.6 cl, 5 dwg

ethod for jet processing of materials // 2580268
FIELD: technological processes.SUBSTANCE: invention relates to jet cutting of workpiece. Method includes providing forced fluid from nozzle to machined workpiece to cutting Jet. Fluid medium is represented by melted fusible alloy, hydrostatic pressure is increased before forming of cutting Jet. Cooling of cutting jet said molten alloy to its fractional crystallisation. Method incudes providing reduction of cutting jet by passing electric current along it and/or external magnetic field. Collecting partially crystallised spent molten alloy with particles of machined workpiece, is converted into liquid phase is separated particles of processed workpiece from melted alloy and latter is supplied to input of fluid medium circulation.EFFECT: broader technological capabilities.3 cl, 1 dwg

ethod for jet processing of materials // 2580267
FIELD: technological processes.SUBSTANCE: invention relates to jet cutting of workpiece. Method includes compression of fluid processing medium, extrusion from a nozzle to machined workpiece in form of cutting jet with cutting a workpiece, collecting waste processing medium, separation from treated material and fed to input of circulation of fluid processing medium. Fluid processing medium used is a conducting material in form of a solution of electrolytes or fused fusible alloy or molten low-melting metal. Electrically conducting material is compressed by passing at cutting jet of electric current and magnetic field.EFFECT: result is minimisation of cut width.4 cl, 1 dwg

Apparatus for cutting and bevelling plastic pipe // 2578333
FIELD: manufacturing technology.SUBSTANCE: invention relates to machines for cutting pipes. Machine for cutting pipes and mowing its ends comprises two lower and two upper support rolls to support pipe with possibility of its rotation. Machine includes two guide wheels between two lower rolls. Machine also contains tool for cutting pipe. Method of cutting pipes and mowing its ends comprises clamping pipe between rolls to produce its ellipsoidal transverse motion. Cutting tool is pressed to surface of rotary pipe for end cut. Turned guide wheel for supporting pipe during cutting in one position.EFFECT: technical result is achieving high accuracy, controllability and reliable support during cutting of pipes and treatment of its ends.10 cl, 3 dwg

Insert for food product grinders // 2575267
FIELD: process engineering.SUBSTANCE: claimed insert comprises the first inserts device for food product grinding including the first punch meant to extrude food product being ground through the insert. The first inserts device is located in the first zone of inserts while second zone, different from the first one, comprises the second inserts device.EFFECT: ease of grinding.15 cl, 2 dwg

Device for plastic film perforation // 2574757
FIELD: machine building.SUBSTANCE: device for plastic film perforation prevents wastes 15 catching by a cylindrical punch pin 2. The device contains the punch pin 2 with the saw-like blade comprising located alternatively shoulders and depressions. Inside the punch pin a projecting part 5 is located, it is locked in it and projects through vertical beyond the level H1 of the bottom parts 7 of depressions in the direction of the level H2 of the tips 6 of the shoulders. Between the punch pin 2 and the projecting part 5 a ring gap 8 is made. Wherein the drive is made with the possibility of pushing in the plastic film of the projecting part 5 for its insertion in the ring gap 8, and breaks it at the bottom parts of the depressions of the punch pin 2.EFFECT: prevention of wastes catching by the punch pin.6 cl, 12 dwg

Improved slicing // 2574143
FIELD: food industry.SUBSTANCE: device contains a cutting head, a blade holder with a slot therein, the first knife element, positioned between the cutting head and the blade holder and having the first cutting edge, and the second knife element having the second cutting edge and passing through the blade holder slot so that the first and the second cutting edges are mainly orthogonally relative to each other.EFFECT: automated high-rate device for preset size potato slicing for packaging.14 cl, 9 dwg
