Tolerances
The tolerance of position of the profiles is +/- 0,5 mm. During the
welding process a bead of polyurethane of about 0,5-1 mm
develops at the meeting point between the profile and the belt.
Should it be necessary for the application, it is possible to remo-
ve it with a mechanical machining.
It is possible to attach profiles on all ELATECH
®
and ELA-flex SD
™
polyurethane belts for conveying, handling and positioning
applications.
Pitch
It is recommended to chose the pitch of the profile correspon-
ding to the belt profile or multiple. This allows to minimize the
effects of the belt overall length tolerance on profile spacing.
Position
Profiles position may be over the tooth or not over the tooth. Belt
Flexibility is maximised when the profiles are applied over the
tooth.
Arc of contact
It is to be noted that the belt's arc of contact may be restricted by
the jointed profile. It is therefore recommended to select profiles
with the minimum allowable thickness "U".
Ordering
When ordering it is necessary to indicate: type of belt (width, profile, pitch, length), the belt length in number of teeth, the belt and
profile drawing with the number and the pitch of the requested profiles
Special execution
On demand it is possible to produce special belts with special machining both on the teeth and on the back of the belt.
