<p>There is disclosed apparatus for feeding sheet material sequentially on demand to processing machinery having a take-up mechanism (12) comprising a feed table (10) having a gate (11) and upon which sheets (5) may be stacked against the gate (11) which allows only the lowermost sheet to pass therebeneath, means driven by a servo-motor (21) to advance the lowermost sheet beneath the gate (11) to the take-up mechanism (12), a sensing means (32) between the gate (11) and the take-up mechanism (12) to detect the passage of the leading edge of the sheet, a microprocessor (30) which receives data indicating the position of the take-up mechanism (12) and from the sensing means (32) and programmed to control the servo-motor (21) to ensure that the leading edge of the sheet presents itself to the take-up mechanism (12) at the correct instant.</p> |
