Abstract
A method produces a flexible shaped strip (18), made of plastic, for fixing cushion cover (12) to a cushion component (10). The cushion component is formed of a foam material and includes a longitudinal channel (20) for insertion of the shaped strip (18). The shaped strip has, at least partly, a slip preventer to increase the tear resistance form the cushion component (10). The anti-slip component or slip preventer is made of a plastic softer than that used for the shaped strip (18), and is, at least partly, arranged around the outer surface of the shaped strip.
Claims34
A method for producing a flexible shaped strip for securing a cushion covering to a cushion component formed of foam material and provided with a longitudinal passage for engaging the shaped strip, comprising the steps of:
- forming the shaped strip from plastic material for engaging the longitudinal passage in the cushion component and securing the covering to the cushion component;
- and
- providing a slip-preventer at least partially on an exterior periphery of the shaped strip, the slip-preventer being a plastic material softer than the plastic material of the shaped strip;
- whereby, the slip-preventer increases tear resistance of the shaped strip to resist inadvertent removal of the shaped strip from the longitudinal passage in the cushion component.
A method for producing a flexible shaped strip for securing a cushion covering to a cushion component formed of foam material and being provided with a longitudinal passage for engaging the shaped strip, comprising the steps of:
- forming the shaped strip from plastic material, the strip having a top surface with a longitudinal slot, a fastener received in the slot and coupled to the shaped strip, and longitudinal interlocking members on side surfaces of the strip defining recessed areas between the interlocking members;
- and
- providing a slip-preventer on said top surface of the strip, the slip-preventer being a plastic material softer than the plastic material of the shaped strip to reduce slippage between the strip and the foam material and to increase tear resistance of the shaped strip to resist inadvertent removal of the shaped strip from the longitudinal passage in the cushion component.
A method for producing a flexible shaped strip and securing a cushion covering to a foamed cushion material having a longitudinal passage for engaging the strip, comprising the steps of:
- forming the shaped strip from a first plastic material, the strip having a top surface with a longitudinal slot, a fastener received in the slot and coupled to the shaped strip and to the cushion covering material, the shaped strip having a plurality of longitudinal interlocking members on side surfaces;
- applying a second plastic material on a surface of the shaped strip to provide a slip-preventing material on the shaped strip, the second plastic material being softer than the first plastic material to decrease slippage between the shaped strip and the foamed cushion material;
- and
- inserting the shaped strip into the longitudinal passage of the foamed cushion material such that the second plastic material directly engages the foamed cushion material.
