ABSTRACT:
The invention relates to a tape applicator head for dispensing tape onto a working surface for the construction of primarily structural parts, and to a method of laying tape onto a working surface.
The tape applicator head includes a housing which is preferably displaced relative to the working surface. The housing includes a tape dispensing outlet where at least one tape dispensing structure has a tape engaging surface which imparts a tension to the tape as the tape applicator head is displaced relative to the working surface to drive the tape through the tape head. Preferably, two tape dispensing blocks are mounted to the housing at the tape dispensing outlet adjacent to each other. These blocks define spaced, symmetrically oriented surfaces which alternately engage the tape and impart the noted tension thereto as the tape applicator head is displaced in two opposing directions relative to the working surface. With this latter arrangement, the orientation of the tape applicator head is maintained unchanged. In addition, the symmetrically oriented surfaces extend outwardly from the tape dispensing outlet substantially parallel to the working surface with the minimum clearance between the working surface and the symmetrically oriented surfaces being less than the thickness of the tape, so that the tape is compressed or compacted as it is dispensed onto the working surface.
According to the method, the tape is compressed or compacted, as noted above, and folded at each end of a tape laying pass so that a continuous layup can be rapidly produced.
