Cut technologies Exact cutting – cost savings

Function

The upper and lower blade shafts are driven by a three-phase motor via a multi-stage spur gear. Different transmission ratios or the use of frequency-controlled three-phase drives allow infinitely variable adjustment of the cutting speed to the required production speed.

Area of use

The main area of application of cut technologies is production systems for paper, foil, textiles, carpet, non-woven fabric and felt webs. Installation of the cutting systems primarily takes place after the last process step before rewinding.

Application

The web cutting device can be used for horizontal and vertical web travels. Slant the web cutting device by 15° for an optimum cutting position. The cutting speed of the cutting systems should be approx. 5 to 10 % greater than the web speed. A web guider in front of the cutting unit optimizes cutting and prevents the web from running away from the blades.

Function

Cutting systems for circular cutting systems cut the web with a circular blade. With circular blade cutting, a disc blade is driven by a three-phase motor in the direction of web travel. An integrated support table ensures a defined cutting position.

Area of use

The circular cutting system is a cost-effective solution for center cuts of non-woven, woven and knitted fabrics.

Application

The web must be run flat by guide rollers both in front of and behind the cutting station. The cutting speed should be 5 to 10 times greater than the production speed.

Function

Textile tube goods with a drop stitch must be cut exactly in this reference line. Using a drop stitch matrix sensor, these are detected safely using the transmitted light principle and fed to the position controller as the actual position. The digital position controller continuously compares the target and actual values and constantly controls the motorized, swiveling guide basket. Using a hand wheel, this can be adjusted to the desired tube diameter. The tube-shaped knitted fabric is opened precisely in the drop stitch with cutting technology systems.

Area of use

In the textile finishing process, knitted fabrics produced in a tube must be cut open along the drop stitch for further processing. In so doing, the cutting technology systems allow an exact cut.

Application

Normally, with a textile tube, the available excess is twisted and the tube is fed to the tube slitter from above. In so doing, the pre-entry path should be at least 3 m.    

Function

The top blade is powered via a geared motor and carries the spring-mounted bottom blade.The device is positioned in a user-friendly manner using a motor at the touch of a button or with automatic follow-up according to the web edge.

Minimal edge waste is only achieved when the web edge is fully unrolled. E+L can offer an integrated mechanical spreading unit (E+L patent) for this and, alternatively, a pneumatic solution for its cutting systems.

Noise-dampened side channel compressors are available for the removal of any edge waste.

Area of use

The edge cutting technology is used at the outfeed of the following systems: Tenter, compactor and sanfor systems.

Application

At the end of the machine, the web is removed from the pins with an initial path roller. Two further path rollers form the cutting level. See graphic alongside.
