Rotary punching of film, foil, paper, cardboard and nonwovens
For 75 years, Schober has been constantly developing, refining and optimizing punching technology in the printing, packaging, hygiene and pharma industries. Rotary punching technology is used when the particles to be removed are too small for a cutting process or cause difficulties in removal. Rotary punching solutions are used in laboratory operations and industrial production - either as a stand-alone offline solution or inline in processing systems. The classic workflow (unwind, punch, cut & rewind) can be maintained even with a wide variety of materials. Burr-free with material widths of up to 2000 mm and speeds of up to 800 m/min. Waste can be safely removed by the anvil cylinder even with extremely narrow punching patterns (with hole diameters of 0.5 mm).

Punching units from Schobertechnologies
Maximum precision and efficiency
Punching units from Schobertechnologies are particularly suitable for the production of profiles and special punchings. They consist of a stable, high-precision cast iron frame and have high-precision bearings. Perfect punching with paired materials (carbide, Longlife, HSS or Super CR) guarantee long operating times under maximum stress for working widths of up to 1,800 mm and working speeds of up to 800 m/min. Integration into existing production systems is also possible without any problems.

Questions & Answers
You can perform a simple test with a commercially available hole punch. If the material can be punched, the chances are good. For further tests, you are welcome to send us material samples in consultation, which we can punch for you on our premises. For further tests, we have a test facility at our disposal.
Paper and cardboard from approx. 30 to approx. 600 gr/m2, films and foils from approx. 20 µm to 500 µm, thin metals from approx. 20 µm to 150 µm, depending on the stability and release properties of the material.
Depending on the product image, the structure of the punching tools is defined. For narrow hole spacing, we use special punch holders with plate hole discs. For wider hole spacing, we use interchangeable punches and dies.
If the tool design permits and it is economical, punches and die segments can be manufactured that allow regrinding. If not, at least ideally the punches and dies can be exchanged. This is particularly useful for standard stock items. With the tight hole spacing, the tool may need to be replaced if it is worn.
In principle, this is possible, although in such a case we can only guarantee the professional manufacture of the tool, but not its function.
If it is a repeat order for a Schober unit, this is possible. For third-party products, we can only guarantee the professional manufacture of the punches and bushings, but not the function.
In principle, almost all shapes (round, rectangular, oblong, freeform) from 0.5 to 30 mm can be punched, although a punching test is recommended in advance and minimal radii in the corners are necessary.
The punching waste is pressed by the punch into the die tool. From there, it can be extracted. Depending on the requirements, Schobertechnologies can supply the appropriate extraction system or the customer can realize this on site with a local system builder.
Schobertechnologies can provide the punching unit with a drive gear or provide a shaft journal to which the customer attaches a coupling with drive motor. Schobertechnologies also supplies drive units for integration into customer equipment.
Our punching units are modular, and in most cases they are adapted to the customer's requirements.
If space allows, this is possible in most cases.
The service life depends on the material to be punched. Depending on the run size and punching geometry, Schobertechnologies offers different materials for punches and dies. From SuCR, HSS, Longlife to carbide, if possible.
