Central taping
machine –
binding head
The taping machine is designed as
a central spinner and is suitable for
binding core strand bundles with
polyester yarn.
The achievable length of twist of
the wound reinforcement helix is in
the region of two to four times the
diameter of the strand bundles. The
maximum inner diameter for strand
bundles is 30mm.
The central taping machine consists
of a hollow shaft with a mount for
a yarn case and/or a yarn spool. A
generously-sized hood enables easy
access and changing of the spool.
During operation the spool can be
observed through a viewing window
and the hood can be opened
upwards from the operating side
and is electromechanically locked
during operation. The central taping
machine is available in left and right-
handed versions.

Zwick scores top marks
for not marking the specimen
The Zwick Roell Group, is pleased to announce that they have developed a new
product which will revolutionise the measurement of strain. Designed for both the
measurement of young’s Modulus and strain at specimen failure using only one device,
the world’s most technically advanced extensometer laserXtens makes no contact with
the specimen under test and requires no specimen marking.
For research and development applications, the laserXtens brings major benefits due to
its high resolution, accuracy and flexibility, whilst for production control especially using
robot technology, the lack of specimen marking and operator involvement enables cost
effective, safe and easy to use operation.
The laserXtens meets class
1 of ISO 9513 (Class B2 of
ASTM E83), and is designed to
test materials in applications
where a contact extenso-
meter might be unsuitable
due to its physical contact
with the specimen or the
whiplash experienced at
specimen failure.
It also enables the testing
of complex component shapes
which would preclude the
attachment of a traditional
contact extensometer.
Due to their mechanical
construction traditional clip-
on extensometers have limited
capability when testing small
components. The laserXtens can measure strain with a gauge length as low as 1.5mm.
An optional transverse measuring system enables the measurement of r values.
The features of the laserXtens are totally integrated into Zwick’s testXpert® software and
make the total testing system very powerful and easy to use.
Zwick believes that the laserXtens extensometer will bring major benefits to the metal,
composite, plastics, and rubber industry, and component testing in the aerospace,
automotive, medical, and the building industry.
