Embodiment Construction
[0029] The machined material or flat substrate used to produce the packaging (not shown), in this case a continuous web (eg flat cardboard). Such as figure 1 As shown, the machine comprises a substrate processing unit 1 for processing a web 2 . The feeding or unwinding direction of the web 2 ( figure 1 The arrow F) in is along the longitudinal direction, which indicates the upstream and downstream directions of the processing unit 1 . The front and rear positions are defined with respect to the lateral direction as the side of the driver or operator and the side opposite the driver or operator, respectively.
[0030] The machine may have a web unwinder, units such as printing assemblies, means for controlling the printing quality and documentation, web guiding means, and other units upstream of the processing unit 1 .
[0031] Processing unit 1 is a unit for embossing, hemming and cutting. The web 2 reaches the unit 1 at a constant speed through the upstream transverse sid...

Abstract
An arrangement for transforming a planar support (2) comprises: - first and second rotating cylindrical transformation tools (16, 17), arranged and cooperating together to transform 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), - adjustment means (42) in the form of spacers (43, 44, 46, 47) having an inclined face (48) and sliding (S) to adjust the respective distance (e, e1, e2) between the first and third bearings (26, 29) and between the second and fourth bearings (27, 31), so as to set a radial gap (20) between the two tools (16, 17). The adjustment means (42) comprise two spacers (43, 44) interposed between the first and third bearings (26, 29), and two bearings (46, 47) interposed between the second and fourth bearings (27, 31). In another solution, either an alternative to or working 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 to the first thread (58) and engaging with a tapped hole (63) in the spacer (43).
Description
technical field [0001] The invention relates to an adjustable processing device for processing flat substrates in a machine for producing packaging and provided with two cylindrical processing tools. The invention also relates to a processing cassette for flat substrates comprising adjustable processing means for said flat substrates. The invention relates to a processing unit for processing flat substrates, which has a processing cassette for flat substrates. The invention relates to a processing unit for processing flat substrates comprising at least one adjustable processing device for flat substrates. The invention also relates to a machine for producing packaging from a flat substrate comprising a processing unit for processing the flat substrate. [0002] The machines used to produce packaging are designed to make boxes, which after folding and gluing form the package. In said machines, an initially flat substrate, such as a continuous roll of cardboard, is unrolled a...
