The holder has a sleeve which can be pressed into a bore in the sidewall shell and, arranged in the sleeve, a helically-spring-mounted, coaxially movable pin. The pin has a pin head which, in an initial position, projects beyond an end of the sleeve with the force of the spring and on which a foil can be positioned on the mold surface. The pin, in an end position, is movable into the sleeve counter to the force of the spring such that the pin head end remote from the pin is aligned with the end of the sleeve. The pin head forms a clearance fit with the sleeve. The clearance fit is such that the pin is movable in the sleeve but no rubber material can ingress into the sleeve. ## Claims ### Claim 1 A holder for the arrangement of a foil on a mold surface of a sidewall shell of a vulcanizing mold, the holder comprising: a cylindrical sleeve configured to be pressed into a bore in the sidewall shell; a helical spring; a coaxially movable pin arranged in said sleeve and helically-spring-mounted via said helical spring; said cylindrical sleeve having a first sleeve end; said pin having a first pin end; said pin having, on said first pin end, a cylindrically formed pin head which, in an initial position, projects beyond said first sleeve end with a force of said helical spring and on which a foil can, via a corresponding punched-out portion, be positioned on the mold surface of the sidewall shell; said pin head having a first pin head end remote from said pin; said pin, in an end position, being configured to be movable into said cylindrical sleeve counter to the force of said helical spring such that said first pin head end is aligned with said first sleeve end; said pin head, with a pin head region facing toward the pin and in its initial position, being configured to form a clearance fit with said sleeve; and, said clearance fit between said pin head and said sleeve being selected such that said pin is movable in said sleeve but no rubber material can ingress into said sleeve between said pin head and said sleeve. ### Claim 2 (depends on 1) The holder of claim 1, wherein said clearance fit in the initial position is formed over a length of 0.8 to 2 mm. ### Claim 3 (depends on 1) The holder of claim 1, wherein said clearance fit in the initial position is formed over a length of 1.0 to 1.3 mm. ### Claim 4 (depends on 1) The holder of claim 1, wherein said pin head has a length of 2.5 to 5 mm. ### Claim 5 (depends on 1) The holder of claim 1, wherein said pin head has a length of 4.0 to 4.3 mm. ### Claim 6 (depends on 1) The holder of claim 1, wherein said clearance fit in said end position between sleeve and pin head is formed over the entire length of the pin head. ### Claim 7 (depends on 1) The holder of claim 1, wherein said sleeve has a length lying in a range from 5 to 10 mm. ### Claim 8 (depends on 1) The holder of claim 1, wherein said sleeve has a length of 7.5 mm. ### Claim 9 (depends on 1) The holder of claim 1, wherein: said pin head has a pin head length and a blind bore arranged coaxially with respect to said pin; and, said blind bore is formed at least over a depth which corresponds to at least 0.5× said pin head length. ### Claim 10 A vulcanizing mold comprising: a sidewall shell having a mold surface; a holder configured to arrange a foil on said mold surface of said sidewall shell of the vulcanizing mold; said holder being disposed in said sidewall shell; said holder having a cylindrical sleeve configured to be pressed into a bore in the sidewall shell; a helical spring; said holder further having a helically-spring-mounted, coaxially movable pin arranged in said sleeve; said cylindrical sleeve having a first sleeve end; said pin having a first pin end; said pin having, on said first pin end, a cylindrically formed pin head which, in an initial position, projects beyond said first sleeve end with a force of said helical spring and on which the foil can, via a corresponding punched-out portion, be positioned on said mold surface of said sidewall shell; said pin head having a first pin head end remote from said pin; said pin, in an end position, being configured to be movable into said cylindrical sleeve counter to the force of said helical spring such that said first pin head end is aligned with said first sleeve end; said pin head, with a pin head region facing toward the pin and in its initial position, being configured to form a clearance fit with said sleeve; and, said clearance fit between said pin head and said sleeve being selected such that said pin is movable in said sleeve but no rubber material can ingress into said sleeve between said pin head and said sleeve. ### Claim 11 (depends on 10) The vulcanizing mold of claim 10, wherein the vulcanizing mold includes at least two of said holders arranged in said sidewall shell.
