Copper Strip and Copper Foil Wrapping Machines

Here the wrapping material is conductive. Copper strip or copper foil is wound onto a conductor, a shield or a joint to create a continuous conductive path over a length, which is how shielding terminations and busbar wraps are made. Because the material is metal, the machine behaves differently from a tape wrapper: tension has to be controlled so the strip does not deform the substrate or spring back, and the wrap must overlap consistently or the connection resistance varies along its length. Specify the strip width and thickness, the substrate, the overlap and the required wrap length. This page also absorbs the copper foil wrapping line, which was the same operation under a different name.
