ABSTRACT:
For the construction of an insulating wound body 8 for electrical insulation purposes, in an installation 50 for the formation of a stack 24, sheets 21 and/or precut sheets blanks 21' are prepared from a web of material. The sheet stack 24 precedes the winding apparatus 10 and the winding material is supplied in a manner such that the width of the sheets corresponding to the winding width coincides with the length of the sheet segment, and the length of the sheets corresponds to the width of the web. The winding material is taken by a perforated conveyor 9 revolving around rolls (in the running direction of the winding apparatus 10), and the insulating sheets 21 and/or sheet blanks 21' are entrained by the segment of the conveyor belt between a lower roll 1 and the preceding reversing roll 3 and wound with edge to edge contact, without gaps, onto a conductor or inner tube 5 freely supported between the stationary lower roll 1 and upwardly mobile upper roll 2, without tensile stresses.
