摘要

Electrical and mechanical means are provided in combination for detecting and preventing irregular conditions in an article handling machine. Means are also provided for sequentially starting a machine used with a supply of articles to avoid the running of a machine when an irregular condition exists in the machine. One embodiment comprises a combination including a sensing means located between a receiving means and a package supply work station to detect an irregular package feed condition. A means responsive to the sensing means will stop the feeding of packages into the receiving means thereby preventing damage to the wrapping machine. Various specific structures of the sensing means and responsive means are disclosed. The sensing means and responsive means may be used in any apparatus for conveying articles at predetermined intervals.
