SUBSTANCE: invention relates to production of tire from spliced strips. First strip is cut-off and placed on unloading conveyor. After cutting of said first strip second strip is cut off and placed on said conveyor. Thereafter, said strips are spliced. Between cutting of first strip and placing of second strip on unloading conveyor, second strip is retained at unloading conveyor. Expected clearance between first strip end and second strip end to be spliced therewith is measured. Depending upon said measured clearance said first strip is displaced relative to second one so that first strip end stays at required position relative to second strip. Now, second strip is placed on unloading conveyor.

EFFECT: higher precision of splicing.

Dismantled pipe is heated to 970-1150°C at its transfer through straight-through inductor at the rate of 30-150°C/s and cut in helical line at inductor exit. Strip blank results therefrom. Cutting is performed in cutting-off pass between two rolls their rotational axes being turned through an angle relative to the pipe lengthwise axis. Magnitude of said angle is predefined from cited equation subject to pipe radius and strip blank preset width. Then, blank is cooled in guide at the rate of 15-45°C/s to temperature of 950-860°C and fed to continuous rolling mill. Blank is rolled to rolled 5.0-12.0 mm diameter wire at 830-910°C.

SUBSTANCE: invention relates to the technology of making complex holes using a laser beam, particularly a through hole for film cooling of a turbine component. At the first step, the internal part (7) of the hole (1) is made from the surface (12) to the opposite internal surface (13) of the substrate (4) using a laser (22) located in a first angular position (1) and simultaneously making a diffuser (10) part. The diffuser (10) residue (16, 18, 28) is removed at the next second and third steps. At the second step, the angular position of the laser (22) is changed to a position (II), different from angular position (I), and the laser is moved to the angular position (II) until the lateral side (17a) of the diffuser (10) is open and part of the volume (18) of the residue (16, 18, 28) remains. At the third step the angular position of the laser is changed from the angular position (II) at the second step so as to remove said residue (18). The angle in the angular positions (I, II, III) is defined as the angle between the middle line of the laser beam (25) and the surface (12) around the film cooling hole (1).

EFFECT: using a laser in three different angular positions relative to the processed substrate significantly simplifies the making of complex holes in the substrate.
