Abstract
A method of producing a roll boot from an injection-moldable elastomer, comprising the following steps: injection-molding a basic member having a cylindrical portion and a widened portion; turning the basic member inside out; folding the widened portion outwardly so that it partially comes to lie outwards of the cylindrical portion, forming a roll wall.

A method of producing a roll boot from an injection-moldable elastomer, comprising the following steps:
- injection-molding a basic member (21) having a cylindrical portion (22) and an widened portion (23);
- turning the basic member (21) inside out;
- and
- folding the widened portion (23) outwardly so that it partially lies outwards of the cylindrical portion (22), forming a roll wall (23′).
A method of producing a roll boot from an injection-moldable elastomer, comprising the following steps:
- injection-molding a basic member (31) having a cylindrical portion (32) and two widened portions (33, 43) which adjoin said cylindrical portion (32) at both ends;
- turning the basic member (31) inside out;
- and
- folding the widened portions (33, 43) outwardly, so that they partially lie outwards of the cylindrical portion (32), forming roll walls (33′, 43′).
A method of producing a roll boot from an injection-moldable elastomer, comprising the steps of:
- injection-molding a basic member (21) having a cylindrical portion (22) and a widened portion (23), the cylindrical portion (22) including, at its free end, an inner annular groove (24) for receiving a clamping band, the widened portion (23) comprising a conical shape, an inner annular bead (25) at is free end, and a decreasing wall thickness from the cylindrical portion (22) to its free end;
- turning the basic member inside out such that the annular groove (24) and annular bead (25) are outwardly facing;
- and
- folding the widened portion (23) outwardly so that it partially lies outwards of the cylindrical portion (22), forming a roll wall (23′).
A method of producing a roll boot from an injection-moldable elastomer, comprising the steps of:
- injection-molding a basic member (31) having a cylindrical portion (32) and two widened end portions (33, 43) adjoining the cylindrical portion, each widened portion (33, 43) comprising a conical shape, an inner annular bead (34, 35) at its free end, and a decreasing wall thickness from the cylindrical portion (32) to its free end;
- turning the basic member (31) inside out such that the annular beads (34, 35) are outwardly facing;
- and
- folding the widened portions (33, 43) outwardly so that they partially lie outwards of the cylindrical portion (32), forming roll walls (33′, 43′).
