Abstract
Fiber reinforced tape is manufactured by moving the tape through a first area while looping a thread on one side of the tape in a plane transverse to the direction of movement of the tape. Each end of the loop is supported by retractable supports as it is formed. After formation each end of a single loop is moved into the plane of the tape to deposit the thread against the tape and the thread is then secured to the tape. A machine for manufacturing fiber reinforced tape comprises a cross-belt moving in a closed loop transverse to the direction of movement of the tape with the cross-belt having a carrier for the thread and means at each end of the cross-belt that move in and out of the plane of the thread to form and support the ends of the loop at each end of the cross-belt as the thread is carried by the cross-belt. The machine further comprises means for moving each end of the loop into the plane of the tape to deposit the thread on the tape in a zig-zag pattern with the ends being held in place by a vacuum belt that moves in the same direction as the tape. Rollers secure the thread to the tape.
