Two powerful die-cutters with high productivity for larger formats, equipped with light barrier activation of the cutting stroke. The machines are used for medium and large-scale jobs and process materials and articles of all types. The maximum cutting size for model BL is up to 220 x 260 mm, for model BLS is up to 230 x 320 mm.
The robust machine design reflects the increased punching power. The hydraulic equipment is integrated within the machine body. The construction and function of both models are identical except for the size of the machine body – due to the variations in cutting size.
Activation of the cutting stroke:
By activating the electronic light barrier. The cutting stroke is activated automatically after the operator has inserted the stack of material and his/her hand has been withdrawn from the punching section. The machine stops if the operator breaks the light barrier during the cutting process.
The machines are supplied with 5 (BL) or 6 (BLS) adjustable clamping arms, waste slitters and holders which are fitted into the clamping arms, thus being able to reach any required position for slitting the waste. The number of waste slitters needed is determined by the material, size and contour of the product to be die-cut. The sliding door on the rear of the machine facilitates fitting of the die and the waste slitters. This offers access to the cutting section from both the control and rear side.
The die-cutters are most commonly used for cutting contours of large-sized labels, brochures, children’s booklets, credit and loyalty cards, for die-cutting in a two-up system and for counter-pressure cutting with special material for inmould labels.
The machines process high volumes of all types of products.
The pneumatic mobile counter-pressure unit for model BL or BLS is easy to fit to the die-cutter in place of the delivery tray. The trolley facilitates the removal and storage of the delivery tray which can be refitted again quickly for jobs without counter-pressure. Changeover time approx. 20 minutes.
The die is especially manufactured for counter-pressure cutting with a movable matrix of plastic or aluminium inside the die. The counter-pressure unit is connected to a compressed air supply. The material is placed in front of the die with the projecting matrix and is held vertically in the die for stabilization during the hydraulic cut. When the ram reaches the end of its stroke, the finished material is pushed back into the feeding tray by the pneumatic counter-pressure cylinder, from where it is removed
This reduces the throughput of the machine by approx. half.
