Abstract: A method for protecting a unit for converting a web substrate to limit a jam of the substrate inside the unit, the unit converting the substrate when the unit is stopped, in a packaging production machine: the steps of: detecting at the outlet of the unit that the converted web does not come out; stopping a motor of an infeed arrangement to prevent the substrate from entering the unit; stopping a motor of a feathering drive; and simultaneously stopping the machine, and guiding the substrate to an accumulation storage.

Abstract: A detection system for detecting double sheets being supplied to a lateral positioning device (100) for a sheet element (20, 20′) in a sheet element processing machine. The machine has a drive system including a cam disk (174) and a cam follower lever (172). The detection system includes a detector lever (130) mounted so as to be displaceable between a sheet receiving position and a detection position. The detector lever (130) has a sheet sensing end (132) for engagement with an upper face of the sheet element (20, 20′) when being in the detection position, and a position detector end (133) for cooperating, when being in the detection position, with a position detector (140) adapted for generating a signal dependent on the thickness of the sheet element (20, 20′), and further includes a raising lever (170) for raising the sheet sensing end (132) of the detector lever (130). The raising lever (170) is mounted on the cam follower lever (172) of the sheet element processing machine. Further disclosed is a sheet element processing machine including a detection system as outlined above, mounted in an introduction station (10) upstream of a processing station.

Abstract: An arrangement for transforming a planar support (2) includes first and second rotating cylindrical transformation tools (16, 17), cooperating to convert the support (2), first and second side bearings (26, 27), holding the first tool (16) for rotation (Rs), third and fourth side bearings (29, 31), holding the second tool (17) for rotation (Ri), spacers (43, 44, 46, 47) having an inclined face (48) and slidable (S) to adjust the respective distances (e, e1, e2) between the first and third bearings (26, 29) and between the second and fourth bearings (27, 31), to set a radial gap (20) between the two tools (16, 17). In another solution, either as an alternative to or in cooperation with the first solution, the spacer (43) is moved (S) by a differential screw (57) having a first thread (58) that engages with a tapped hole (59) in an integral part (61) of one of the bearings (29) and a second thread (62) different than the first thread (58) and engaging with a tapped hole (63) in the spacer (43).
