80 results about "Curling" patented technology

Curling is a sheet metal forming process used to form the edges into a hollow ring. Curling can be performed to eliminate sharp edges and increase the moment of inertia near the curled end. Other parts are curled to perform their primary function, such as door hinges.

Concurrently removing sheet charge and curl

Decurling a charged sheet and removing charge from the charged sheet prior to stacking, includes forming a nip between a roller and a compliant surface and applying pressure between the roller and compliant surface so that the nip has a decurling shape and when the nip engages the sheet it will perform a decurling function; and moving the charged sheet through the nip while the compliant surface has an AC voltage applied thereto so that a first side of the charged sheet is in contact with the compliant surface and has its charge substantially dissipated, whereby charge substantially remains on a second side of the charged sheet in contact with the roller and curling of the charged sheet is reduced. The method further includes using at least one non-contact charge removal device to remove charge from the second side of the charged sheet; and stacking the discharged sheet.
