Abstract

A method and apparatus for the production of wound elements. The method comprising: providing a plurality of first electrical web elements; disposing at least one of the first electrical web elements upon a conveying element, wherein a first or second face of the disposed first electrical web elements is disposed in a face to face relationship with the conveying element; providing a plurality of second electrical web elements; disposing at least one of the second electrical web elements upon the conveying element at a predetermined spacing from the disposed first electrical web elements and in a face to face relationship with the conveying element, wherein the predetermined spacing is at least as long as the length of the first electrical web element; and disposing an electrically insulating separator web element in a face to face relationship with the disposed electrical web elements.

First claim

What is claimed is:

1. A method for forming a power cell core; the method comprising steps of:
a. providing a plurality of first electrical web elements, each having a first face, a second face, a length and a width;
b. disposing at least one of the first electrical web elements upon a conveying element, the conveying element having a conveying direction and a cross-conveying direction, wherein the first face of the at least one of the first electrical web elements is disposed in a face to face relationship with the conveying element;
c. providing a plurality of second electrical web elements, each of the second electrical web elements having a first face, a second face, a length, and a width;
d. disposing at least one of the second electrical web elements upon the conveying element at a predetermined spacing from the at least one of the first electrical web elements and in a face to face relationship with the conveying element, wherein the predetermined spacing is at least as long as the length of the at least one of the first electrical web elements, and wherein the first face of the at least one of the second electrical web elements is disposed in a face to face relationship with the conveying element;
e. disposing each of the first and second electrical web elements upon the conveying element at a distance upstream of an adjacent one of the first and second electrical web elements such that the distance between adjacent ones of the first and second electrical web elements progressively increases as the first and second electrical web elements are disposed upon the conveying element;
f. disposing an electrically insulating separator web element in a face to face relationship with the second face of each of the first and second electrical web elements disposed upon the conveying element;
g. gripping at least one of the first electrical elements with a winding element, the winding element being disposed on a carousel; and
h. rotating the winding element about a first axis of rotation while rotating the winding element with the carousel about a second axis of rotation to wind a combination of the first and second electrical web elements and the electrically insulating separator web, wherein rotation of the carousel about the second axis of rotation initially carries the winding element and the first axis of rotation away from the conveying element to create clearance between the rotating winding element and the conveying element.

2. The method according to claim 1 , comprising, prior to winding the combination of the first and second electrical web elements and the electrically insulating separator web element, conveying the combination of the first and second electrical web elements and the electrically insulating separator web element across a gap between the conveying element and the winding element.

3. The method according to claim 1 , comprising, prior to winding the combination of the first and second electrical web elements and the electrically insulating separator web element, cutting the electrically insulating separator web element.
