10.8 Repair Procedures
The operating time before significant wear will occur with WEXXAR packaging machines depends
upon the service duty to which the machine is subjected, and can vary widely between different
customers. Many wear points are quite simple (bushings, rod ends, etc.), and the corrective
action is self-evident. Some repair jobs requiring special attention are described in the following
paragraphs. Please also refer to the assembly drawings in the Supplementary Manual, which
contain much helpful information and all necessary part numbers.
10.8.1 Pneumatic Cylinder Repairs
Tie-rod Type
A tie-rod type NFPA-style cylinder is used to drive the separator motions. Repair kits to
replace all wear components in this cylinder are available. When ordering repair kits,
ensure that the correct cylinder is specified.
Band-type (Rodless)
A rodless cylinder is used to drive the magazine pusher mechanism. This cylinder can
be overhauled to replace all wear components.
Non-repairable Type
Non-repairable cylinders are used to drive the flap folders (major and minor), the head-up
latch, and the magazine feedbelts. These cylinders must be replaced when worn out.
High Power Type
High power cylinders are used for the mast and discharge pusher. Repair kits are
available from your Wexxar representative.
High Speed Type
High speed cylinders are used for the jaw and injector motions.
WARNING!
Before undertaking repair work, ALWAYS ensure that the
Main Air Pressure and Electrical Supplies are locked OFF.
