1. A touch fastener strip comprising:
- a strip-form base comprising a first face and a second opposing face extending between lateral edges;
a plurality of fastener elements extending in an array from the second face of the strip-form base;
a magnetically attractable material attached to the strip-form base;
a flexible backing secured to the first face of the base and extending beyond the lateral edges to form selvedges; and
wherein the backing is shaped such that the selvedges extend, in an unloaded state and in the direction of the fastener elements, beyond the second face of the strip-form base.

Abstract
Touch fasteners for use as mold inserts in molding seat foam buns include a strip-form base a magnetically attractable material disposed on the strip-form base; and film selvedges biased to depend downward from the strip-form base toward the fastening side, such that they will be deflected away from the fastening side as the fastener is pressed into an associated trench.

17. A method of forming a seat foam bun, the method comprising:
-
providing a mold cavity having a shape corresponding to a desired shape of the foam bun; positioning a touch fastener in the mold cavity, the touch fastener comprising a strip-form base comprising a first face and a second opposing face;
a plurality of fastener elements disposed in an array on the second face of the strip-form base;
a magnetically attractable material attached to the strip-form base;
flexible lateral selvedges extending in an unloaded state beyond the second face of the strip-form base in the direction of the fastener elements at an angle θ
between 10 and 80 degrees from the plane of the strip-form base; anddelivering a foamable resin into the mold cavity to form a seat foam bun, the resin flowing across the selvedges of the touch fastener. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A seat foam bun comprising:
-
a foam bun; and positioned onto the foam bun, a touch fastener comprising a strip-form base comprising a first upper face and a second lower opposing face; a plurality of fastener elements disposed in an array on the lower face of the strip-form base; a magnetically attractable material secured to the strip-form base; and flexible lateral selvedges extending beyond the strip-form base and being deflected upwards between about 10 and 160 degrees from an unloaded downward angle θ
of between 10 and 80 degrees relative to the plane of the strip-form base.
