A method for selectively feeding rolls of paper coming out of a log saw unit (10), wherein the log saw unit (10) comprises (n) feeding channels (12) for feeding logs (11) towards a cutting device (13) provided at the outlet with (n) unloading belts (14) in a number equal to the feeding channels (12), comprises a step of generating a stop signal relating to a portion of a packaging unit downstream of the log saw unit (10) further to the detection of accumulation of rolls (11′) and/or of stopping of a packaging machine, as well as a step of attributing said stop signal to a feeding channel/sub-group of feeding channels (12) operatively associated with the portion of the packaging unit, called “feeding channels/sub-groups of feeding channels (12) subject to stopping”, wherein the method—upon receipt of the stop signal—comprises at least the steps of: ending the cutting of the log (11) in progress on all of the (n) feeding channels (12) of the log saw unit (10), selectively stopping the forward movement of a new log (11) towards the cutting device (13) just in the feeding channels/sub-groups of feeding channels (12) subject to stopping through the stopping of the forward movement of the carriers (15) of the carrier device (16) of the feeding channels/sub-groups of feeding channels (12) subject to stopping, proceeding without interruption in the operative feeding channels (12), namely those not subject to the stop signal, with the cutting of the logs (11) in succession.
1) Method for selectively feeding rolls of paper coming out of a log saw unit (10), wherein said log saw unit (10) comprises (n) feeding channels (12) for feeding logs (11) towards a cutting device (13) provided at the outlet with (n) unloading belts (14) in a number equal to the feeding channels (12), characterised in that said method comprises a step of generating a stop signal relating to a portion of a packaging unit downstream of the log saw unit (10) further to detection of accumulation of rolls (11′) and/or of stop of a packaging machine, as well as a step of attributing said stop signal to a feeding channel/sub-group of feeding channels (12) operatively associated with said portion of the packaging unit, called “feeding channels/sub-groups of feeding channels (12) subject to stopping”, wherein said method—upon receipt of said stop signal—comprises at least the steps of:
7) Log saw unit for logs of paper comprising a number equal to (n) feeding channels (12) for feeding logs (11), a cutting device (13) for cutting rolls (11′) of paper and a number equal to (n) unloading belts (14) in a number equal to the feeding channels (12) arranged downstream of the cutting device (13) and suitable for transferring rolls (11′) towards a packaging unit, characterised in that it comprises a control unit for processing a stop signal relating to a portion of the packaging unit downstream of the log saw unit generated further to detection of accumulation of rolls (11′) and/or of a stop of a packaging machine and for attributing said stop signal to a feeding channel/sub-group of feeding channels (12) operatively associated with said portion of the packaging unit, called “feeding channels/sub-groups of feeding channels subject to stopping”, and in that said feeding channels/sub-groups of feeding channels (12) comprise an advancement carrier device (16) equipped with actuators (17) that are independent from each other and selectively controllable by said control unit, like for example single servomotors for each feeding channel/sub-groups of feeding channels (12).
