A powered dispenser for dispensing individual paper towel segments from a continuous roll of paper provided with spaced lines of tearing comprises a housing, a support for the roll of paper, a feed mechanism, and a control device. The control device senses the presence of a user to activate the feed mechanism, controls the amount of material which is dispensed from the housing for any one cycle, and prevents further dispensing of the paper until the previous segment is separated from the roll. The control device detects the leading edge of the paper to initiate monitoring of the length of paper to be dispensed to prevent any cumulative error in dispensing the segments.

1. A dispenser comprising:a housing having a discharge opening; a support within the housing for supporting a continuous strip of sheet material having a plurality of spaced tear lines defining leading and trailing edges of individual removable segments, with an outer segment having a free leading edge and inner segments which in turn become outer segments as adjoining outer segments are removed; a feed mechanism for repeatedly advancing the sheet material to advance, in first and second intervals, successive outer ones of said segments through the discharge opening and out of the housing; a sensor for repeatedly detecting arrival of a said leading edge of the advancing sheet material at a first position defining the end of said first interval and the beginning of said second interval, as the sheet material is repeatedly advanced toward the discharge opening; and a control device for receiving a signal from the sensor indicating a said arrival of a said leading edge at said first position, and for terminating the operation of the feed mechanism when a said leading edge of the sheet material has further advanced from said first position a predetermined amount, to repeatedly place said spaced tear lines at a second position that is variable within a space defined between the feed mechanism and said first position in relation to variations in the lengths of said segments, said second position defining the beginning of a said first interval of advancement for a next adjacent segment, when it is in turn dispensed.
