Abstract
A method of forming electrical structures embodying the following steps: (a) providing a carrier sheet having electrodes formed thereon in spaced relation along a length dimension of the sheet, and (b) spirally rolling said sheet about a roll-up axis to bring the electrodes into radial registration, the rolling including transmitting roll-up force to the carrier sheet from a web being translated endwise, adjacent the carrier.
Claims23
In apparatus to fabricate a multilayer tubular electrical component that comprises a laminated electrode and carrier sheet assembly, by wrapping the assembly about a mandrel the combination comprising
- (a) a first support roll,
- (b) a second support roll extending generally parallel to the first support roll,
- (c) a roll-up force transmitting web wrapping at least partially about the support rolls and which web is translated while the rolls rotate to wrap the sheet about the mandrel as the sheet feeds progressively between the mandrel and web, and
- (d) yieldable tensioning means operatively connected with the web to tension the web so that the mandrel and the carrier sheet being wrapped thereon are urged by the web toward a nip defined between said rolls, said tensioning means being carried by one of the rolls and being connected to a portion of the web between the tensioning means and the other of the rolls,
- (e) said mandrel about which the web partially wraps as the web is translated from wrapping engagement with one roll to wrapping engagement with the other roll,
- (f) and heating means for heating the web wrapping about the mandrel.
The method of forming electrical structures, that includes:
- (a) providing a carrier sheet having electrodes formed thereon in spaced relation along a length dimension of the sheet,
- (b) spirally rolling said sheet about a roll-up axis to bring said electrodes into radial registration, said rolling including transmitting roll-up force to the carrier sheet from a web being translated endwise, adjacent the carrier,
- (c) controllably exerting yieldable tension on said web as it translates endwise,
- (d) providing back-up roll surfaces against which the web is urged during said rolling, in response to the tension exertion,
- (e) locating a mandrel to receive roll-up of the carrier sheet with the carrier sheet located between the mandrel and the web, and
- (f) transferring heat via the tensioned web to the carrier sheet as it is rolled up about the mandrel.
In apparatus to fabricate a multilayer tubular electrical component that comprises a laminated electrode and carrier sheet assembly, by wrapping the assembly about a mandrel the combination comprising
- (a) a first support roll,
- (b) a second support extending generally parallel to the first support roll, and
- (c) a roll-up force transmitting web wrapping at least partially about the first roll and for local translation while the first roll rotates to wrap the sheet about the mandrel as the sheet feeds progressively between the mandrel and web,
- (d) yieldable tensioning means operatively connected with the web to tension the web so that the mandrel and the sheet being wrapped thereon are urged by the web toward a nip defined between said roll and said second support, said tensioning means operatively connected to the support and to the web to controllably urge the mandrel and sheet wrapped thereon toward said nip,
- (e) said mandrel about which the web partially wraps,
- (f) and heating means for heating the web wrapping about the mandrel.
The method of forming electrical structures, that includes:
- (a) providing a carrier sheet having electrodes formed thereon in spaced relation along a length dimension of the sheet,
- (b) spirally rolling said sheet about a roll-up axis to bring said electrodes into radial registration, said rolling including transmitting roll-up force to the carrier sheet from a web adjacent the carrier, one of said sheet and web undergoing endwise translation relative to the other,
- (e) controllably exerting yieldable tension on said web during said endwise translation,
- (d) providing controllably spaced back-up roll surfaces against which the web is urged during said rolling, in response to the tension exertion,
- (e) locating a mandrel to receive roll-up of the carrier sheet with the carrier sheet located between the mandrel and the web, and
- (f) transferring heat via the tensioned web to the carrier sheet as it is rolled up about the mandrel.
