History
Hermann STÄUBLI began his career in a Horgen (Switzerland) firm, where he performed maintenan-
ce on weaving machines. His technical skills were noticed by another industrial entrepre-
neur, Rudolf Schelling. Together, they opened a construction and repair machine shop. Then,
in 1892, the "Schelling & Stäubli" company was created on the banks of Lake Zurich. Very rapidly, the
firm became specialised in the weaving industry, and particularly dobbies, for which numerous pa-
tents were produced.
Following the death of Rudolf Schelling, Hermann STÄUBLI took control of the company with his
brother, Robert Stäubli-Kaspar. They created a new subsidiary in France in order to be closer to their
customers.
In 1909, STÄUBLI Frères located in Faverges and their 30 employees began producing dobbies.
Still today, STÄUBLI develops and manufactures its cam motion and their corresponding harness mo-
tions.

Lubrication with oil
Housing
Maximum number of lifting units that can be installed in the cam motion.
Open shed position
Position of the cam motion enabling the frames to be placed in movement depending
on whether the weave is in the high or low position. This position corresponds to the
stop position of the frames, enabling the weft to be inserted.
Closed shed position
Position of the cam motion enabling the fames to be placed in movement at cross-shed
position. The other frames remain in high or low position.
Levelling of the harness frames

2 - DESCRIPTION TMD10-DTC002.1
The assembly you have acquired consists of the following elements:
- A cam motion.
- A transmission.
2.1 - INTELLECTUAL PROPERTY TMD10-PPI001.1
STÄUBLI cam motion type machines and the optional products delivered with the machines are
protected by trademarks, patents and patent applications.
STÄUBLI is a registered trademark.
All copyright violations will be prosecuted.
2.2 - CHARACTERISTICS TMD10-CRT001.3
2.2.1 - CAM MOTION CHARACTERISTICS TMD10-CRT002.2
The cam motion can accommodate up to 10 levers on an 11-frame shaft.
The cams are available with ratios of 4, 5 or 6 picks, which enables the production of fabrics with
a repeat of 2, 3, 4, 5 or 6 picks.
The speed ratio of the cam motion's cam shaft in relation to that of the weaving machine may be
1 to 4, 1 to 5 or 1 to 6, depending on the gears used in the control housing.
The cams can be symmetrical (enabling a weft or a warp effect, according to how they are as-
sembled), or asymmetrical (one single warp or weft effect possible, per asymmetric cam).
The cam motion is equipped with a hydraulic leveling system, which allows:
-to bring the warp threads to their minimal tension, when the weaving machine is at a standstill,
by placing the levers at cross-shed position.
-to facilitate program changes by separating the rollers from the cams.
2.2.2 - COMPLIANCE WITH REGULATIONS TMD10-CRT004.1
This cam motions complies with the provisions in directive 2006/42/CE concerning quasi-machi-
nes.
2.3 - IDENTIFICATION TMD10-IDF001.1
For all inquiries, order for spare parts, or service request, please indicate the type and serial
number of the cam motion concerned, located on the nameplate.

4.1.3 - CHECK THE OPERATING CONDITIONS TMU35-CFO001.1
The maximum speed of the cam motion is a function several parameters:
-Cam profile.
-Frame travel.
-Maximum reed space.
-The weight of the frames.
-The weight of the heddles.
