Hose molding device

Claim 2

A collar for use with a mandrel and for molding an end of a rubber hose comprising: a stretchable elastomeric sleeve having at least one circumferential element end that defines a molding surface; and means integrally molded at and extending inwardly of the internal diameter of the sleeve for deformably removably attaching the sleeve to the mandrel.

Claim 3

The collar delineated in claim 1 wherein the attaching means comprises an integrally molded circumferential bead near the circumferential element end.

Claim 4

The collar delineated in claim 2 comprising an integrally molded flange at the circumferential element end.

Claim 5

The collar delineated in claim 3 wherein the flange has a generally flat surface which defines the molding surface.

Claim 6

The collar delineated in claim 3 wherein the flange has a generally frustro-conical surface which defines the molding surface.

Claim 7

The collar delineated in claim 1 comprising means integrally molded at the external diameter of the sleeve for handling the retainer during use.

Claim 8

The collar delineated in claim 6 wherein the handling means comprise longitudinally oriented ribs.

Claim 9

The collar delineated in claim 7 wherein the length of the sleeve is greater than the diameter of the sleeve.

Claim 10

The collar of claim 1 comprised of integrally molded silicone rubber.

Claim 11

The retainer of claim 9 wherein the silicone rubber has a shore A durometer of the range of 50 to 85.

Claim 12

A mandrel for curved hose comprising: a generally cylindraceous member with at least one curved portion between two generally straight first and second end portions; a radial collar secured to the cylindraceous member near the first end portion, the collar defining a first hose end molding surface; and means disposed near the second end portion below a surface of the cylindraceous member for retaining a removable collar that defines a second hose end molding surface.

Claim 13

A mandrel for curved hose comprising: a generally cylindraceous member with at least one curved portion between two generally straight first and second end portions; a radial collar secured to the cylindraceous member near the first end portion, the collar defining a first hose end molding surface; and means disposed near the second end portion below a surface of the cylindraceous member for retaining a removable collar that defines a second hose end molding surface.

Claim 14

The mandrel of claim 11 wherein the retaining means is a circumferential groove.

Claim 15

The mandrel of claim 12 wherein the axial distance between the radial collar and circumferential groove corresponds to a predetermined hose length.

Claim 16

An assembly for curing hose comprising: a generally cylindraceous member with at least one curved portion between two generally straight first and second end portions and having a circumferential groove near the second end portion; a radial collar secured to the cylindraceous member near the first end portion, the collar defining a first hose end molding surface; and a removable collar comprising a stretchable elastomeric sleeve having at least one circumferential element end that defines a second hose end molding surface, and means integrally molded at and extending inwardly of the internal diameter of the sleeve in the form of a molded circumferential bead near the circumferential element end wherein the sleeve has a diameter less than the second end of the cylindraceous member, and the bead is nestable within the circumferential groove, the sleeve stretched over the second end portion and a bead retained in the circumferential groove.

Claim 17

An assembly for curing hose comprising: a generally cylindraceous member with at least one curved portion between two generally straight first and second end portions and having a circumferential groove near the second end portion; a radial collar secured to the cylindraceous member near the first end portion, the collar defining a first hose end molding surface; and a removable collar comprising a stretchable elastomeric sleeve having at least one circumferential element end that defines a second hose end molding surface, and means integrally molded at and extending inwardly of the internal diameter of the sleeve in the form of a molded circumferential bead near the circumferential element end wherein the sleeve has a diameter less than the second end of the cylindraceous member, and the bead is nestable within the circumferential groove, the sleeve stretched over the second end portion and a bead retained in the circumferential groove.

Claim 18

A collar comprising: an elastomeric sleeve having a circumferential element end that defines a molding surface; and an integrally molded circumferential bead near the circumferential element end.

Claim 19

A collar comprising: an elastomeric sleeve having a circumferential element end that defines a molding surface; and an integrally molded circumferential bead near the circumferential element end.
