Both standard papers and digital prints with sensitive surfaces - such as coated papers, glossy papers or picture prints - should be able to be processed as gently as possible and without marking. This is what the SF 1500 plus from HEFTER Systemform stands for, with suction air extraction from the top and blast-air assisted separation of the sheets. The transport in the machine is also particularly gentle thanks to the suction belt.

With the stored programmes, work can be carried out quickly and conveniently - with minimum set-up times at the same time.
Of course, the SF 1500 plus can also be precisely adjusted to individual folding applications. Up to three special programmes can be stored. The smallest sheet format (W x L) is 120 x 210 mm, the largest 330 x 488 mm (SRA3+).
The speed of the SF 1500 plus suction-air folding machine can be adjusted in five stages to suit the job. The maximum speed is up to 18,000 cycles/h.
The SF 1500 plus folding machine can be equipped with the following options, thus extending its range of application:
