Types Of Profiles
1) The dmin specification for the belts, the lateral profile and the sidewall must be taken into consideration when determining the drum diameters. The greastest value is the limiting factor and a smaller diameter may not be used. The specifications for dmin are standard values determined at normal ambient conditions of 20oC / 50% humidity.
Lower temperatures require larger diameters.
2) Can be used only in conjunction with sidewalls.
Recommended splice method when using longitudinal profiles 1-ply types with splice film
reinforced with gauze2 + 3ply types Z-overlap nad overlap splice Indented longitudinal profoles are available.
Concerning service life we recommend using whole profiles that are not indented, as the identation can cause splits at the bottom of the profile.Further special profiles available on request.
Types of Splices The appropriate splicing method for individual belts depends on the belt type, the application and the individual operating conditions. Decisive criteria for selecting the splicing methods are, in addition to the splice reliability, also the flexibility of the splice and the properties required by the application technology.
Detailed splicing instructions available on request.
Hot-press method : A hot-pressed splice provides the greatest durability and flexibility. Following versions are possible :
Z - Splice (1) : Meets the most stringent requirements for uniformity of thickness. Very flexible splice, especially well suited for knife edge belts. Standard splice for 1 and 2-ply belts types. Standard splice angle is 90o (60o is possible). Stepped Z-Splice (2) : Similar properties as the Z-Splice. Also Suitable for harsh operating conditions. Possible on various 2 and 3-ply belt types. Splice angle is 90o Wedge Splice (3) : Splice type used for PVC and PU and both side fabric type of belts. Splice angle is 90o Overlap Splice (4) : Especially well suited for 2 and 3-ply belt types with duroplastic surface materials. Splice angle is 90o or 80o Cold-Press Method : It is possible for customers to cold-press wedge or overlap splices independently when fitting or repairing on-site. Please note that splice strength and flexibility are limited.
