Differences and Opportunities of Overlock, Crowlock and Flat Machine
Overlock is a stammers of a chain stitch machine.
Overlock - simultaneously cuts the threads and coats the cut ... Cream of fabrics must be prepared, i.e, cut off an excess (elapse), otherwise the fabric can tighten into the mechanisms and an overlog will fail due to the knife failure or looper.
In Overlock can be used from 2 to 5 yarns.
4 - and 5-thread overlocks are recommended for knitting processing.
Flat Machine (Facility) It is used to sewing products from knitted, strongly stretched tissues. The chain seam that is formed as a result of the interlacing has a stretch property in length. The dispenser machine performs a specific seam, which is called fragrant
So, the dispenser performs only one function - stitches the knitted cloth without trimming.
Externally, the sewing machine is similar to the sewing, but it works completely differently. In the fraud, as in Overlock, there is no shuttle device, and the threads from the coils are immediately served on the needle and the looper.
In contrast to overlocks, the filament of the levyer's looper is woven with needle not around the edge of the material cut, but in any product you need.
The decorative plays woofers can create a beautiful decorative finish. Clothes, decorated with decorative seams, looks more beautiful and stylish. It is very convenient to make the niza and sleeves, to make the niza and sleeve, to sew a rubber band in sports club, make a bump or sewing the piece of jack.
Covers (from English CoverLock) - A special sewing machine that combines the functions of the overlock and the decomposition with the ability to make decaying (flat) seams when processing knitwear.
Coverlock is an indispensable assistant when working with knitwear! Only on the koverlock can be made upper stuck (i.e., the seams with a layer on top and bottom) and the 5-thread-rapid-overlapping seam.
The upper blast is a decorative decoration of a dispenser seam, in which the additional thread is stacked on the front side and the seams on the front and invalid side look the same.
Left- 5-threading rapidly - revision seam.
Visual differences
Visually to distinguish the Coverlock from the cutting and the more overlock is very simple. It is enough to pay attention to the length of the departure of the sleeve. There is practically no overlock, since it simply does not need - overlock coats only cut edges of the fabric. The spreading machine departure the sleeves is the same as the sewing machine, because when laying a connective or decorative linga, a place is required for the product.
Technical differences of overlock and croellok
Overhead only cuts and coats the edges of the material. Coverlock, in addition to these two functions, performs one more: due to the presence of an additional device - the looper of the chain stitch, or the wrister, is able to make a decaying seam (for knitwear). Thus, Coverlock combines the functionality of the overlock and the dispenser machine.
Overlock has two, and Coverlok has three loovers.
Overlock from two to five workers. Crowlock can be up to ten, due to which they can perform a huge number of decorative seams.
When working with koverlock, certain skills and time are required to switch the device from one function to another.
Coverlock is more expensive than overlock, he is more cumbersome.
Covers, depending on the model, can have an additional table, touch screen and many other modern devices to facilitate work.
