Perforating Rules
Our Perforating Rules are produced with exact pitches. The perforation is burr-free. Gap and cut of standard pitches are wider or identical to the Rule’s thickness. On top of the standard types, we produce asymmetrical pitches as well as gap and cut smaller than the material’s thickness.


Asym. Perforating

In case of Asymmetrical Perforating Rules, pitches and the number of repetitions are free to choose. Long cuts, gaps or special-micro perforating parts can be produced in one piece. The Speedi products, which are asymmetrical as well, also allow new folding and stripping
possibilities for consumer/shelf-ready packaging


Special-Micro-Perforating Rules

These Rules, also known as "invisible perforation", provide a unique, very fine perforation. Depth of gap is variable, depending on the thickness of material being diecut. Pitches are produced according to customers‘ requirements. Standards can be produced in coils. Standards in 0.6mm depth are: 30tpi (0.4:0.4mm), 40tpi (0.3:0.3mm), 50tpi (0.25:0.3mm), 60tpi (0.25:0.25mm) and 72tpi (0.2:0.2mm), produced from hardness H5.

Crease/Cutting Rules, flat crease

To achieve functional bending edges in corrugated board it is necessary to combine a cut and a crease. In addition to standard pitches we produce asynchronous pitches as well. The creasing top is without any burr in order to minimize fractures in the liner.

 

Crease/Cutting Rules, round crease

To achieve functional bending edges in corrugated board it is necessary to combine a cut and a crease. This rule is designed for applications which afford a round creasing part. In addition to standard pitches we produce asynchronous pitches as well.

Speedi Products

Particular perforating products, mainly used in corrugated, requiring intense consultancy service - designed for extremely difficult applications, i.e. separation of the blanks, folding and tearing technologies. Please contact us for further information or for consultancy

 

Glue Flap Rules

This rule roughens the surface of the diecut product and supports the gluing process, e.g. on box flaps. Waves and pitches according to customers‘ request.

 

Zipper Rules

A Zip-A-Tear rule, being used pairwise to produce a tear away strip in a box. Standard is 2/3 straight part; 1/3 angled part at a 45 degree angle.
A huge variety of other types is available on request.

Tissue Perforating Rules

These Rules are for fast opening of shelf ready packaging. Angles and depths of perforation can be chosen according to customers‘ requests. It is also known as Handhole Perforation.
