INDEX TAB FORMING SYSTEM
An index tab forming system sequentially forms index tabs to a plurality of sheets without replacing a blade die. The index tab forming system includes a rotary die cutter 5 on which a long blade die that can form an index tab at any position of the sheet in the conveyance direction is mounted. Furthermore, the index tab forming system includes a rotational speed calculation unit configured to calculate the rotational speed of a conveyance roller pair 37 based on the rotational position of a die cut roller 50, a sheet position detection signal provided by a sheet detection sensor 40, the number of times of sheet conveyance, and a shift distance between respective index tabs and a conveyance roller control unit configured to control the rotational speed of the conveyance roller pair 37 based on the calculated rotational speed.
METHOD FOR SELECTIVELY FEEDING ROLLS OF PAPER COMING OUT OF A LOG SAW UNIT AND RELATIVE LOG SAW UNIT
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.

SHEET PROCESSING APPARATUS HAVING PUNCHING UNIT FOR PUNCHING SHEETS AND IMAGE FORMING APPARATUS
A sheet processing apparatus includes: a punching unit configured to punch a sheet conveyed; a movement unit configured to cause the punching unit to move in a direction intersecting with a conveyance direction of the sheet; a detection unit configured to detect a first conveyance position which is a position in a width direction orthogonal to the conveyance direction of the sheet; and a control unit configured to obtain size information of the sheet, determine, based on the size information, a second conveyance position in the width direction when the sheet is conveyed, and by comparing the first conveyance position and the second conveyance position, control whether or not to execute an avoidance process that causes the punching unit to move away from the sheet.

Product roll cutting and handling mechanism and method
A hands-free paper product dispenser has three separate IR emitter and sensor circuits, two controlling the length and/or number of sheets of paper cut and dispensed, and the third used both to safety interlock the cutter mechanism and to control retention of each cut sheet by the dispenser until removed from the dispenser by a user. A novel cutting mechanism and associated upper and lower pinch plates are employed to both hold the paper during cutting and assure a straight and unfrayed cut.
