Winding of tape into pads

摘要

The winding of tape into pads is effected on a machine which controls the tension in the tape as it is laid onto the pad by a lay-on roller which also drives the rotation of the pad. A pad is a spiral winding of tape in which each turn of tape is laid directly on top of the previous turns. The machine includes a series of cores one for each tape mounted on a shaft for independent rotation of each core relative to the shaft. The tape is directed from common guide rollers to a series of individual arms one for each tape with each arm being mounted on a shaft for individual adjustment along the length of the shaft to a position associated with the particular core. The shaft drives a lay-on roller at an outer end of the arm and the arm can pivot about the shaft to accommodate changes in diameter of the package as built. The use of lay-on rollers which are all driven at the same speed ensures a constant tension in the tapes even if the tapes are deviated outwardly so as to increase the spacing between the tapes relative to the original web from which the tapes are slit.
