Transporting individual roving bobbins manually from the roving frame to the ring spinning machine is labor-intensive and often results in damage to the roving. The answer to this problem is a roving bobbin transport system. Today, therefore, various solutions are available for bobbin transport from roving frame to ring spinning machine with different degrees of automation to suit customer needs, for example from Rieter, Schönenberger, Electro-Jet and other companies.
Such transport systems have a number of advantages with regard to quality and costs:

Quality

  • elimination of manual bobbin handling
  • elimination of intermediate storage, which can result in damage, soiling and aging of the roving
  • elimination of the likelihood of confusion between different roving bobbins
  • ensuring the application of the “first-in, first-out” principle

Costs

  • space saving
  • quality assurance and enhancement
  • labor savings of up to 25% compared to manual bobbin transport by reducing physical effort, reducing the distance covered by operating personnel, improved access to the machines and improved ergonomics

Fig. 34 shows an example of automatic bobbin transport between roving frame and ring spinning machines. Two separate circuits in the area of roving frame and ring spinning machines guarantee a continuous supply of roving bobbins to the ring spinning machines.
