Fastener tape fabrication equipment and process for manufacturing fastener tape for attachment in an opening in the top of a reclosable plastic bag. A continuous strip of intermediate layer for carrying a continuous strip of profile fastener is provided from a delivery assembly with a constant tension to an applicator assembly. A pair of laterally spaced adhesive surfaces are also carried upon the intermediate layer. The intermediate laye r passes over a generally V-shaped member, mounted upon the delivery assembly, in order to b e folded. The profile is inserted into the fold of the intermediate layer. Circumferential ly grooved wheels then align the profile with the intermediate layer as the intermediate layer and profile are directed into a plurality of sealing bars upon the applicator assembly to fo rm the fastener tape. A first set of sealing bars seal the profile to the intermediate layer and a second set of sealing bars seal the adhesive surfaces together to form a peel seal on the intermediate layer. The resulting fastener tape is then collected on a windup roll. |
