Embodiment Construction

[0024] figure 1 The schematically shown grooving plant 1 basically comprises a driven, horizontally supported transport roller 11 and a plurality of rollers 54.1 to 54.8 which run continuously around and are spaced apart from each other, forming the inlet 14 and the outlet 15. The belts 51 which in some cases wrap around the transport roller 11 and the grooving knives 72 which are arranged between the belts 51 at a defined distance from the drum shell. The cardboard blank 2 conveyed by the conveying device 101 to the inlet 14 is pressed onto the roller shell by the belt 51 in an efficient conveying manner (foerderwirksam) and is transported along the conveying direction 11 a from the center of the conveying roller 11 during a rotation of the conveying roller 11 through approximately 180°. The inlet 14 at the lower apex leads to the outlet 15 at the upper apex and is guided there past a grooving knife 72 , where a correspondingly designed grooving knife 71 removes, for example,...

Abstract

The invention relates to a device (1) for grooving cardboard blanks (2, 3) which operates on the roller principle and has a driven, horizontally supported transport roller (11) and multiple Belts (51) continuously surrounding the roller and spaced apart from each other partially wrap around the conveying roller forming an inlet and an outlet and press the cardboard blanks efficiently conveyingly onto the roller shell. Grooving knives are arranged between the belts at a defined distance from the drum shell. Setting: The belt and / or the grooving knife is located on a first support that can be reciprocated radially relative to the transport roller between a working position and a rest position. In the rest position, the belt or the grooving knife can be easily adjusted. In addition, a plurality of second carriages are provided, which are displaceable relative to one another separately and relative to the transport rollers and which have at least rollers defined for guiding and tensioning, preferably individual webs.

Description

technical field [0001] The invention relates to an apparatus for slotting cardboard blanks. Background technique [0002] Book covers and boxes for high-value sales and gift packaging consist essentially of cardboard glued with a facing material. In order to produce bends or sharp-edged flanges, the cardboard blanks are notched at the corresponding points. The groove can have a triangular to rectangular shape in cross-section, which is shaped as chips by the correspondingly opposite blades or disc knives and possibly by an ejector arranged in between or by a single-part shape according to the corresponding cross-section. A special cutter cuts it out of the cardboard. [0003] A cardboard slotting machine of this type is known from CN 101200091 B, in which the belt partly wound around the transport roller is guided by a guide roller and a plurality of deflection rollers respectively and is separated by separate pressing rollers. tension. The guide rollers, which are equip...
