2. Description of Background and Relevant Information [0003] The equipment used for corrugating of sheets is equipped with plural roll stands in their progressive line.

[0004] There are different solutions to produce corrugated pipe. Almost all of them have intricate kinematics and need complicated adjustments to fit pipe diameter or to change pitch dimension. Moreover, most of these apparatus stretch corrugating workpiece, and thus create undesirable stresses in the material.
See, for example, U.S. Patent Nos. 3,690,137; 4,619,131; 5,056,348; 6,073,473;
6,282,939;
6,550,300; 6,789,318.

[0005] An apparatus such as the one disclosed in U.S. Patent No. 4,366,691 includes sliding wheels. However, displacement of these wheels needs very fine adjustment. Moreover, making more than two corrugated waves at the same time needs too intricate kinematics and operation complexity. Finally, the changing of pitch dimension is fully impossible.

DETAILED DESCRIPTION OF THE INVENTION
= FIG. 1 is a longitudinal view illustrating rotating shafts with sliding wheels and elastic collars at the start position in accordance with the present invention;
= FIG. 2 is a longitudinal view illustrating rotating shafts with sliding wheels and elastic collars at the finish position;
= FIG. 3 is a cross-sectional view illustrating the possible third shafts and it location.
= FIGS. 4a, 4b, and 4c are cross-sectional views illustrating corrugated sleeves with different pitches (4a) or (4b)/and (4c) different depth of corrugations.
DETAILED DESCRIPTION OF THE INVENTION
[0009] Shown in FIGS. 1 and 2 is an embodiment in accordance with this invention. Apparatus for the fabrication corrugated sleeves or sheets comprises of spline shafts 1 and 2 mounted on a rotating mechanism (not shown) with possibility to rotate said shafts in an opposite direction in relation to each other. In addition, said rotating mechanism has the possibility to displace said shafts toward and away from each other. Further, said spline shafts are provided with needed quantity of sliding wheels 3 and 4, double wheels 5 to keep sleeve/sheet 6 edges in fixed position relatively to said wheels 5, and fixed to the shaft 1 or 2 restricting wheels 7 and 8. Elastic collars (or springs) 9 are located between said wheels 3 and 4.
[0010] FIG. 3 shows another embodiment of this invention, where said rotating mechanism is provided with a third shaft 10 similar to shafts 1 and 2 with possibility to shift manually said shaft 10 in accordance with said sleeve/sheet diameter (plain sheet has infinite diameter). Said shaft 10 serves as guide for moving/rotating workpiece 6, especially when the middle wheel from set of wheels 3 or 4 is fixed to the shaft 1 or 2 and respective middle wheel 11 on the shaft 10 is fixed to said shaft [0011] The aforementioned apparatus operates in the manner described below.
[0012] First, the apparatus for the forming corrugations in sleeves or sheets is provided with the certain quantity of sliding wheels 3 and 4 and with certain length of elastic collars 9. Double wheels 5 flanks in position depend on initial width of the workpiece 6. Restricting wheels 7 and 8 are fixed on the shaft 1 and 2. The distance between said wheels 8'slightly bigger than the initial width of the workpiece 6. At the same time, said wheels 7 and 8 compress respective set of the collars 9 with the small initial force.
[0013] In the case (see FIG. 4a) when, for instance, a smaller pitch is needed in the middle of said workpiece 6 in order to withstand higher load in this area, just shorter collars 9 should be placed in this middle area. To create deeper grooves in some part of said workpiece (4b), just sliding wheels with bigger diameter should be placed in this area.
[0014] Now, workpiece 6 is placed between shafts 1 and 2, and rotation of the shafts 1 and 2 is started. At the same time, said shafts start to displace toward each other, and said wheels 3 and 4 start to corrugate workpiece 6 by mostly collecting material of said workpiece along said shafts.
