Tangential belts
Sectional tangential belt drives
These types of drive place high demands and
the tangential belt:
the ability to withstand high
mechanical and thermal stress on the belt surfaces �
especially during spindle stop and acceleration precise belt tracking with little
oscillation greatest possible belt flexibility as
well as a simple, reliable endless splice
The properties of the Extremultus A + E line
are used to their fullest advantage on this application. The
highly-modular, flexible belt design saves energy and minimizes
RPM variations in the section of spindles. The precise Z-splice
ensures that the belt tracks with little oscillation, treating
the machinery gently. Yarn quality and service lives of the
drive components increase, energy and maintenance costs drop.
Conventional tangential belt drives
Whether it is twisters, texturing machines,
ring spinning frames, double twisters or cover spinning frames
the following requirements are increasingly important for the
tangential belt:
greatest possible transmission of
effective pull while using the technical properties to the
fullest reduced noise generation as speeds
increase functional reliability, ensuring high
productivity
Highly-modular tangential belts of the
Extremultus A + E line are being used increasingly more often,
in addition to the reasonably-priced, tried-and-tested
Extremultus P line tangential belts.
Tangential belt drives with concave/
convex drive geometry
For the economical mass production of textile
machinery, the design of the spindle section with concave or
convex drive geometry has proven itself time and time again. The
elimination of pressure rollers, the small pulley diameters, the
short take-up ranges and in some cases the fluctuating ambient
conditions shape the requirements for:
precise tracking and low-noise belt
operation belts which save energy and are
flexible highly-modular tension member largely
unaffected by climate, and long belt life
The innovative Extremultus E line provides
the greatest benefits possible for application technology,
setting a new cost/benefit standard for operating and
maintenance costs.
Rotor drive belts for OE machines
Since the infancy of OE spinning technology,
high-efficiency tangential belts from Forbo Siegling have been
closely associated with rapid increase in rotor speeds. Under
the trademark Extremultus GG 20..., milestones have been set in
the development of rotor drive belt technology:
