Abstract:
1. A machine for folding nappy/diaper blanks, comprising: a first conveyor feeding a succession of nappy/diaper blanks toward a second conveyor; a retaining mechanism associated with the first conveyor and engageable with an intermediate area of each blank to retain a first portion of the blank on the first conveyor while allowing a second portion of the blank to pass onto the second conveyor; a transfer mechanism located between the first conveyor and the second conveyor, by which the second portion of the blank is transferred from the first conveyor to the second conveyor, the second conveyor combining with the first conveyor to manoeuvre at least the second portion of the blank to flatten the second portion against the first portion at a point substantially of mutual tangency between the first conveyor and the second conveyor; wherein the transfer mechanism actively engages the second portion of the blank during the transfer from the first conveyor to the second conveyor and is distanced from the second portion once the transfer has been completed; wherein the transfer mechanism comprises an alternating pendulum conveyor movable between a first limit position of proximity to the first conveyor and a second limit position of proximity to the second conveyor for transferring the second portion of the blank.
