Disclosed are apparatus and a method for converting a sheet into a continuous strip, wherein the apparatus comprises a cutting device with one or more cutting members, one or more drives, and a feeding device, wherein the apparatus is provided with one or more sensors for detecting the first longitudinal edge and the second longitudinal edge of the sheet and a control unit that is connected to the one or more drives, the feeding device, and the one or more sensors for controlling the movement of the one more cutting members relative to the sheet based on the detection to create a sequence of cuts to form interconnected sheet sections, wherein the control unit is arranged for variably controlling the strip width.
An apparatus for converting a sheet into a continuous strip, wherein the sheet has a sheet body extending in a longitudinal direction and having a first longitudinal edge and a second longitudinal edge extending on opposite sides of the sheet body, wherein the apparatus comprises a cutting device with one or more cutting members for cutting the sheet along one or more cutting lines and a feeding device for feeding the sheet in a feeding direction and in a feeding plane across the one or more cutting lines, wherein the apparatus comprises one or more drives for providing a relative movement between the one or more cutting members and the sheet, wherein the apparatus is provided with one or more sensors for detecting the first longitudinal edge and the second longitudinal edge and a control unit that is operationally connected to the one or more drives, the feeding device and the one or more sensors for controlling the movement of the one or more cutting members relative to the sheet based on the detection of the first longitudinal edge and the second longitudinal edge by the one or more sensors to create a sequence of cuts in which the cuts are spaced apart in the feeding direction over a strip width and alternately extend in a first cutting direction transverse to the feeding direction and parallel to the feeding plane from one of the longitudinal edges towards and terminate at a transition width short of the other of the longitudinal edges to form a plurality of interconnected sheet sections, wherein the control unit is arranged for variably controlling the strip width, wherein, for each cut of the sequence of cuts, the control unit is arranged for controlling the movement of the one or more cutting members to start the cut at one of the longitudinal edges and terminating the cut at the transition width short of the other of the longitudinal edges based on the detection of said other of the longitudinal edges by the one or more sensors.
The apparatus according to claim 26, wherein the control unit is arranged for controlling the transition width resulting from the second group of cuts to be sixty percent or less of the transition width resulting from the first group of cuts.
The apparatus according to claim 30, wherein the control unit is arranged for controlling the transition width resulting from the second group of cuts to be half of the transition width resulting from the first group of cuts.
