Abstract
A method for applying an elastomer on a sheath (2) includes the step of applying by pad-printing an elastomer layer on a portion (20) of the sheath (2). A pad-printing machine (1) is also provided for implementing the method. The invention can particularly be used for textile sheaths used in the protection of exhaust-gas flow pipes in an automobile.
Claims20
A method of applying an elastomer to a sheath (2) of interlaced filaments, comprising:
- depositing an elastomer layer on a portion (20) of said sheath (2) by a pad printing process, the elastomer layer being adapted to bond the interlaced filaments of said sheath.
A pad printing machine (1), comprising:
- at least one pad printing module (3, 3′, 4) adapted to deposit an elastomer layer on a sheath portion (2);
- a tank containing an elastomer;
- and
- downstream of said at least one pad printing module (3, 3′, 4) cold cutting means (6) adapted to cut said sheath in said portion.
1 more element
A protective sheath, comprising:
- at least two transverse portions (20) including an elastomer layer deposited on the sheath (2), the transverse portions (20) extending all around the tubular surface of the sheath (2) and being spaced from each other and extending over a predetermined length (d′) of the sheath in a longitudinal direction.
