COMPACTeasy: Competitively priced compacting device for high-quality yarns

Rieter
is addressing the market requirements for cost optimization in compact spinning
with its compacting device COMPACTeasy. This mechanical compacting solution can
spin high-quality yarn from all common raw materials at a high productivity
rate. Competitive price and minimal maintenance and energy requirements make
COMPACTeasy the device of choice for spinning mills in India.

While
ring spinning is still the predominant end spinning system in India, there is a
notable trend underway in this market toward converting conventional ring spinning
machines to compact-spinning machines. Improved yarn properties result in
better running behavior in downstream processes and better fabric appearance.
Moreover, there is a growing demand from big brands to use compact yarn instead
of conventional ring yarn. Compact spinning is appreciated for its excellent
yarn quality and high productivity. Saving energy and investment costs are
decisive factors for spinning mills today. Other compacting systems require
both a high level of initial investment as well as considerable operating
costs. By developing the compacting device COMPACTeasy, Rieter’s subsidiary Suessen
is addressing this market requirement for optimized costs (Figure 1).

Covering
Most Applications

COMPACTeasy
is a mechanical compacting solution for all standard applications. It is
attracting customers thanks to its low investment costs. This does not mean
compromising on top-notch yarn quality compared to pneumatic compacting
systems. COMPACTeasy produces yarns with excellent characteristics from all
standard raw materials, such as cotton and man-made fibers, as well as their
blends. With a yarn count range from Ne 20 to Ne 80, COMPACTeasy
covers most applications.

Constant
yarn quality and low maintenance

COMPACTeasy is
characterized by precise fiber guiding in the y-channel of the compactor, which
results in intensive double compacting (Figure 2). This process does not
require any additional energy.

Compared to
other mechanical systems, the compacting channel of COMPACTeasy is much wider,
so it is less prone to clogging. In addition to this, the roller does not
require grinding thanks to the traverse motion of the compactor. This helps to
extend the service life of the components, such as cots or aprons, and
significantly reduces maintenance requirements. The traverse motion system enables
a consistent yarn quality. This provides a considerable advantage over flipping
the front top roller, which is usually required in mechanical systems.

Less Wear and Tear

The
device consists of a front top-roller retainer and the smaller COMPACTeasy
roller. The compactor features the y-channel and the preceding pin and is
located between the two top rollers. The compactor spring uses a low spring
force to press the compactor against the bottom roller. This causes
considerably less wear and tear on the compactor than magnetically loaded
compacting elements.

The
yarn quality is determined by both the y-channel of the compactor and the
integrated pin. It takes effect precisely in the zone of the drafting system
where the fibers have the least guidance. This process reduces yarn hairiness
and increases yarn tenacity. It further improves yarn irregularity and yarn
imperfections.

Fast
Plug-On Plug-Off

COMPACTeasy
can be added to the specifications for new ring spinning machines and supplied
at the same time. Furthermore, it can easily be retrofitted without additional
efforts to existing Rieter ring spinning machines. No additional pneumatic
system or gearing reinforcement is required. COMPACTeasy enables production to
switch from conventional ring yarn to compact yarn by simply installing or
removing the compacting device on a ring spinning machine with
fast plug-on plug-off ability.

Overall,
COMPACTeasy is a very attractive solution for spinning mills due to low investment
costs and no additional energy requirements. The increased yarn tenacity and
consistency in quality, as well as the ability to spin a wide range of fibers
and yarn counts complete the benefits of this mechanical compacting system.
