ABSTRACT:
Disclosed is an improved apparatus for automatically cutting belt loops and removing splices from a loop string material. The apparatus has an input portion for directing loop string material into the apparatus and storing a quantity of the material with a dancer roller. The loop string leaves the input portion and is transported by first and second driven rollers. A splice sensor engages the string between the first and second spaced driven rollers. The splice sensor includes a foot with a reflective surface thereon and a transducer positioned to direct a light beam down to the reflective surface and sense the reflected light beam. The foot is positioned such that a splice moving with the loop string will cover the reflective surface and break the light beam, thereby allowing the apparatus to sense the presence of the splice. A measuring transducer is connected to one of the driven rollers and measures the amount of loop string advanced thereby. A cutter apparatus is actuated responsive to the measuring transducer to cut the loop string into sections having the desired length for belt loops and to remove spliced portions from the loop string. Electronic circuitry is employed to regulate the operation of the cutter apparatus.
