15 contribute.

The advantages of the polyester polyester re, spectral to steel strip, is that it has a saving of 50-60% of the strip, since it saves the use of the linker (gT'apa) and that of the cElrtón. There are many companies ~ ::; a¿ :; manufacture rectified products, aluminum,

On the other hand, with the recommended system, the Venezuelan moves

25 laterally to leave the strap on the material to strap. With this we avoid marking the material to strap as the displacement is llm¡: no and without contact with the strapping material.

30 Moreover, in, The applications of the flej ado ~ ::; to the coils circumferentially, they introduce several elements to retain the strap in the same coil, since the smaller the diameter of the reel to strap o3r, the greater the slogans they will have to de] ar the

At the beginning of the feeding of the strap, this Q "\ lan.za in age (l", ~ second) and 20 subsequently advances in rapid speed around ~ to coil, package, tube, or element to strap until the Jjega arrives at a first det. (18) located on the lower guide plate (82). Once e, L LLe] e has delivered to said detector (18), the advance of the shaft

25 is slower and the encoder (56) counts the distance that the strap must travel until the tip of the strap appears above the jaw (25). That is to say when the strap 11egE said to tector (18) the encoder (56) counts the cli s ta.llc:ia. a r (:; run by flej (:;,
