Abstract
Abstract A flexible belt carrier is provided for use in an apparatus for spray soldering the ends of roll capacitor blanks. The belt may be constructed of silicon rubber and has apertures extending transversely through the belt which are positioned very near to one of its surfaces. A slit or opening is made at each aperture through the web separating the aperture from the nearest surface of the belt. The belt moves in a sinuous path such that when flexed around a pulley in one direction the edges of the slit spread and gap, allowing ready insertion of a blank. When the belt passes over another pulley, the belt flexes in the opposite direction so as to foreshorten the slit surface. The slits are made at an angle acute to the surface of the belt. Therefore, as their surface foreshortens, the walls of the web formed at the slit cam against one another and overlap, thereby fully and tightly encircling the capacitor blank, exposing only the ends thereof. At this point, molten solder is sprayed at the sides of the belt and makes contact with the ends of the capacitor blank, adhering thereto. The belt then passes around another pulley which causes the slit edges again to gap, freeing the capacitor blank which is then ejected from the belt. The flexing of the belt loosens any surplus solder that may adhere to the belt.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
164 words
A method of solder coating the ends of roll capacitor blanks carried in a flexible belt having longitudinally spaced apertures extending transversely therethrough and slits extending angularly from the apertures to one flat surface of the belt to form pairs of flexible flaps enclosing the apertures comprising: loading roll capacitor blanks into the apertures in the belt; flexing the belt in a direction toward the slitted flat surface to move the angular slitted surfaces of the flaps over each other to constrict the apertures and form virtually continuous surfaces about the peripheries of the capacitor blanks; advancing the belt to move the capacitor blanks to a work station; spraying solder at the belt and roll capacitor blanks within the work station; flexing the belt in a direction away from the slitted flat surface to slide and cam the angular slitted surfaces of the flaps over each other and enlarge the apertures; and ejecting the solder-end-coated capacitor blanks from the enlarged apertures in the belt.
Claim 2
Independent Claim
164 words
A method of solder coating the ends of roll capacitor blanks carried in a flexible belt having longitudinally spaced apertures extending transversely therethrough and slits extending angularly from the apertures to one flat surface of the belt to form pairs of flexible flaps enclosing the apertures comprising: loading roll capacitor blanks into the apertures in the belt; flexing the belt in a direction toward the slitted flat surface to move the angular slitted surfaces of the flaps over each other to constrict the apertures and form virtually continuous surfaces about the peripheries of the capacitor blanks; advancing the belt to move the capacitor blanks to a work station; spraying solder at the belt and roll capacitor blanks within the work station; flexing the belt in a direction away from the slitted flat surface to slide and cam the angular slitted surfaces of the flaps over each other and enlarge the apertures; and ejecting the solder-end-coated capacitor blanks from the enlarged apertures in the belt.
Claim 3
Dependent Claim
34 words
A method according to claim 1 wherein the ejecting step is accomplished at least in part by blowing a jet of fluid at the roll capacitor blanks in the enlarged apertures in the belt.
Claim 4
Dependent Claim
53 words
A method according to claim 1 wherein the step of flexing the belt to constrict includes: squeezing the roll capacitor blanks; and conforming the belt to the surface of the roll capacitor blank sufficiently to preclude the passage of molten solder along the side of the roll capacitor blank in the belt carrier.
Claim 5
Independent Claim
190 words
A method of applying a solder spray to the ends of roll capacitors by manipulating a continuous belt having a plurality of transversely extending open-ended slots, said belt having pairs of oppositely disposed sections projecting over the slots with each section having a bevel tip overlying the bevel tip on the other section of each pair, which comprises: moving the belt through a roll capacitor loading station and through a solder spray station; arcuately engaging the unslotted side of the moving belt while passing through the loading station to bend the belt to compress the underside of the belt while flexing the slotted side to spread the projecting sections overlying each slot to open the slots; loading roll capacitors seriatim into each open slot, said flexible belt completely encircling saids capacitors; arcuately engaging the slotted side of the moving belt while passing through the solder spray station to compress the slotted side to move the bevel tips over each other to compress the walls of the slots against the roll capacitors and mask the circumferential surfaces thereof; and spraying solder axially to coat the ends of the compressed roll capacitors.
Claim 6
Independent Claim
190 words
A method of applying a solder spray to the ends of roll capacitors by manipulating a continuous belt having a plurality of transversely extending open-ended slots, said belt having pairs of oppositely disposed sections projecting over the slots with each section having a bevel tip overlying the bevel tip on the other section of each pair, which comprises: moving the belt through a roll capacitor loading station and through a solder spray station; arcuately engaging the unslotted side of the moving belt while passing through the loading station to bend the belt to compress the underside of the belt while flexing the slotted side to spread the projecting sections overlying each slot to open the slots; loading roll capacitors seriatim into each open slot, said flexible belt completely encircling saids capacitors; arcuately engaging the slotted side of the moving belt while passing through the solder spray station to compress the slotted side to move the bevel tips over each other to compress the walls of the slots against the roll capacitors and mask the circumferential surfaces thereof; and spraying solder axially to coat the ends of the compressed roll capacitors.
