Abstract
A method of manufacture comprises the following steps: (a) advancing a fastener tape made of flexible thermoplastic material along a process pathway during an indexing portion of a work cycle, the fastener tape not advancing during a dwell time of the work cycle; (b) during each dwell time, deforming the fastener tape at a first fixed station situated along the process pathway; (c) transmitting light toward the fastener tape at a second fixed station while the fastener tape is advancing; and (d) photodetecting a portions of the transmitted light after some or all of the transmitted light has passed the fastener tape, the photodetected portions of the transmitted light being converted into electrical signals; wherein the distance of the fastener tape advanced in step (a) is determined in accordance with an algorithm that takes into account characteristics of electrical signals acquired in step (d) during earlier work cycles.
