1、 Flexible cutting adaptation direction, both positive and negative directions can be cut separately
1. Single angle circular knives can only be used with one side facing fixed, and reverse cutting is prone to material compression, fuzzing, and deviation;
2. Double angle circular cutter with symmetrical inclined surfaces on both sides, capable of cutting normally when the blade is installed in both directions;
It can adapt to different installation layouts of the upper and lower knife holders, and there is no need to adjust the blade orientation when changing specifications on the production line;
It can be used as an upper blade to match the bottom blade, or directly suspended for cutting films, non-woven fabrics, and tapes.
2、 Compatible with more materials and various working conditions (core multifunctional value)
Suitable materials for covering flexible rolls: BOPP film, release paper, foam, non-woven fabric, rubber, tape, leather, woven fabric, paper.
Thin materials (film, paper): sharp edged edges, flat cuts, not easily stretched or drawn;
There is a certain thickness of elastic material (foam, rubber): the double-sided slopes reduce compression deformation, and the incision is not flattened;
Compared to flat edged circular knives: Flat edged knives are prone to pilling and fuzzing due to the squeezing of thick materials; Compared to single angle knives: Single angle knives tend to deflect when thick materials are compressed on one side.
3、 Support multiple processes: slitting, trimming, slotting, and waste cleaning. One machine with multiple uses
1. Longitudinal slitting of rolls (most commonly used): mother roll slitting, producing narrow strips of adhesive tape, protective film, and non-woven fabric;
2. Edge trimming of sheet/roll material: Cut off irregular burrs and double-sided slopes to avoid edge breakage of the workpiece;
3. Shallow groove pressure cutting/half cutting: adjust the cutting depth to achieve half cutting (only cutting the surface layer, leaving the bottom paper), commonly used in the label and protective film industry;
4. Waste stripping and cutting: The die-cutting industry uses waste cutting knives to easily cut and connect waste materials;
The same blade can be switched between different processes by adjusting the blade clearance and cutting depth, without frequent tool changes.
4、 The knife path layout has strong adaptability and is suitable for complex cutting stations
1. It can be used for continuous cutting in straight lines, as well as short stroke reciprocating cutting;
When multiple blades are arranged in parallel for multi blade cutting, adjacent blades do not interfere with each other;
3. It is suitable for both high-speed continuous slitting (slitting machine) and intermittent die-cutting and cutting machines;
When single angle circular knives are densely installed side by side, the direction of the inclined plane conflicts and the layout is limited.
5、 Additional advantages in service life and operation and maintenance
After one side of the blade wears out, flipping it over and using the other side of the blade doubles the lifespan of the blade; Single angle circular knives can only effectively cut slopes on one side and cannot be flipped and reused;
2. Convenient regrinding and repair: Double sided cone angles are uniformly ground without the need to distinguish between positive and negative angles;
3. Strong universality: Switching between multiple products on one production line can reduce the variety of tool inventory and lower inventory.
