The labeling machine comprises means for feeding a succession of products toward and past a label applying station, means for feeding a series of labels along a path toward the label applying station, a label length monitor including means for counting a predetermined number of given fractional label lengths totaling a whole length greater than the length of a given label and means to control the feed of the label feeding means, a product sensor connected to the control means and starting the feed of the label feeding means each time a product is detected, a label sensor connected to said control means and causing the latter to stop the label feeding means each time the leading edge of a label moves through a given point before said counting means has counted said predetermined number of given fractional lengths, said counting means being operable to cause the control means to stop the operation of the label feeding means if the label sensor has failed to actuate the control means before said predetermined number of lengths has been counted by said counting means. |
