Savios Polar E Premium Automatic Winder is an alternative solution for all those mills where mainly existing ring frames are without automatic doffing. This machine aims at the same winding efficiency of the link solution.

It is indeed recognised that the maximum level of automation on the winding process is achieved by a direct link of the ring spinning frames to the winder. The advantages, already well known, through the continuous automatic transfer of the ring bobbins from one machine to the other are:

  • Yarn quality of the wound package which is preserved being the bobbins prepared and automatically doffed on the ring frames, without any operator handling or loading into separate boxes;
  • higher efficiency on winder;
  • production output flow consistency and timed, as a single machine; and
  • minimisation of winding room personnel.

Most of customers select the link system solution whenever a new mill has to be set, or in alternative, whenever old ring spinning frames must be substituted. As a consequence, the real focus of Savio has been dedicated to propose an alternative solution, for all other mills where mainly existing ring frames are without automatic doffing, with the same winding efficiency of the link solution.

Polar E Premium, has been designed to evenly process those yarn bobbins, whose formation is not originally "favourable" to reach that efficiency, keeping also the minimum number of operators.

Hopper

The capacity has been increased thanks to the "double alternate" bobbin loading system on the peg.

To achieve the full-efficient peg loading rate, bobbins are mechanically spaced, bobbin shape identified by the"profile reader sensor" and properly oriented by the "cross shaped" rotating device.

The "profile reader sensor" detects also the empty tube and diverts it into a separate dedicated collecting box. The enhanced hopper capacity and efficiency, allows a loading rate to cover the winding heads up to 72 spindles.

Peg feeding system

An efficient loading system requires:

The oriented bobbins before be loaded on the relevant peg, are cleaned from any flying attached yarn by an air suction located in each of the two coupling sleeves.

End finder station

Particularly designed to handle bobbins with yarn reserve at the bottom of the tube (ring frames without automatic doffing), the end finder station is provided with a "knife bunch remover" in combination with an air suction blow for the cleaning; contemporaneously the yarn tail is introduced into the tube upper hole to get the bobbin prepared to the winding head.

All above described features of the Hopper/Peg feeding system/End finder station, transform the original "manual doffed" bobbin into a similar one used in the link system.

End finder station layout

The machine design has been focused on the layout of the end finder station as follows:

  • the end finder stations, are distributed along the machine frame and consequently allow the proper balanced distribution feeding capability to the whole machine. The machine can be regarded as a coupling of 2 o 3 single machines; the "centralised end finder system" cannot permit same even balancing.

With this "balanced" solution, Polar E Premium can have up to maximum n¦ 72 winding heads. Their positions being placed separately from the main bobbin/pegs belts flow, do not affect at all the efficiency of the system. Being front-side located, allow an easy intervention of the operator.
