A powered dispenser (10) 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 (25), a feed mechanism (37), and a control device (38). 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. |
