A little bit of care goes a long way
In this page, we would like to show you some of the simple things you can do to keep the efficiency and reliability of your machinery at the optimum. There are no big secrets to it – just a few simple procedures that are well worth remembering.

Keys for Trouble-Free Operation of Wrap System

Belt clearance; belt condition and tracking

Front wrap floor belts – two key checks

Wrap feeding path around lower gate roller is not impeded

Wrap rolls must be lowered for harvesting

Wrap clutch must be operating correctly

Check wrap leader after daily cleaning of machine

Wrap Related Alerts in Cab

"Wrap Misfeed Detected. Wrap dispensed exceeds total wrap length."

"Multiple Wrap Detected. Confirm wrap separation completed."

"Wrapping halted - Wrap length not found. Wrapping halted. Measured wrap length not as expected."

Wrap Troubleshooting

Loose cover-edge

Wrapped rubber roller

Intermittent damage to the tacky wrap

Inadequate or no cover-edge

Edge tear

Wrap torn dramatically

Unwrapped module ejected – wrapping of the starter roll

Partially wrapped module or wrap trailing out of gate after eject

Adhesive deposit on the rubber rollers

Multiple wraps on module with NORMAL Z-lock separation on outer portion

Handling Damage to Wrap

Core Repair

Instructions for TamaWrap™ Core Repair Extension

The core repair extension is a tapered plug which can be inserted into the original core of the TamaWrap™ roll to replace a cracked or damaged core end. The extension has a set of 8-7 grooves that are graduated in diameter, from narrowest to widest. A pair of rubber O-rings is suplied in the kit. Use both the wide black O-ring and the narrow black O-ring as described below

Cut off the damaged end of the core carefully, making sure not to harm the roll of material.
Refer to step 6 for maximum core length.

On the repair extension, slide the wide black rubber O-ring onto the 6th groove in the external grooved section. The narrow black O-ring supplied in the kit should be placed on the short grooved section located in the internal side of the flange.

Insert the repair extension into the core in spiral motion. There should be a slight resistance when inserting the extension. Note: Do not use a hammer to install core repair extension. Damage to the flange will occur.
Caution! leave your fingers out of the core’s hole while inserting the repair extension to prevent injury.

If the repair extension is too loose, move the O-ring to a wider groove and repeat step 3. Moving the O-ring closer to a wider groove will increase the resistance.

The extension should firmly grip the core (Fig. 5).

With core repair extension inserted, measure the overall length of the core by inserting a tape measure through the inside of the core. Overall length should meet specification: 2784-2790mm (109.84 in.-109.66 in.).
Note: Must not exceed maximum length or roll will not install properly.

Reporting Field Issues

Module Truck or Moon Buggy Requirements

A proper module truck loading and unloading of round modules impacts the ability and reliability of subsequent ginning of these modules. Be sure to share this important information with all truck drivers and use the following check list to verify they have the proper equipment to handle the modules:

Module trucks with 12 bed chains must have inside eight chains replaced with Stover RMS chain to prevent damage to the module plastic wrap.

Module trucks with 11 bed chains must have inside seven chains replaced with Stover RMS chain to prevent damage to the module plastic wrap.

As a final check, nonStover RMS chain is only allowed within 17 in. (43 cm) of module truck inside wall surfaces.

If chain tail wheels are the sprocket style, paddle style with sharp points, or narrower than 2 in. (5 cm), replace with wide smooth paddle style tail wheels.

For moon buggys, enough strands of chains must be replaced to the middle of the width to accommodate a 1.5 m (5 ft.) flat portion of a module, regardless of the side to side placement of the module. As with a module truck, no more than 17 in. (43 cm) of non-Stover RMS chain is allowed from the extreme inside width of the moon buggy to prevent damage to the plastic wrap.

Verify accurate synchronization of truck or moon buggy bed to ground speed per manufacturer’s owner’s manual.

Many module trucks have the chain speed biased to run slightly faster than the ground speed. This is not permissible with round modules and will cause cutting on the underside of the modules during loading and unloading.

Do not attempt to load round modules if not properly staged.

Verify that module group and individual modules have been identified per farmer and gin instructions before loading.

Do not add 2”x 4” boards or other spacers to the troughs in between the module truck bed chains. The spacers will increase the friction between the underside of the module and the truck bed and can cause wrap damage.

Daily inspect for and remove any sharp edges on the module truck side panels or other areas where round modules can contact.

Rubber or steel cleat tracks are highly recommended when handling round modules in wet or sandy conditions.

Loading Procedure

Load or unload modules with continuous and even truck speed. Starting, stopping, and varying speed will cause slip of the modules relative to the chains.

Chain tail wheels should clear ground surface by approximately 1 in. (25 mm). Excessive digging is not required and just adds to foreign matter brought to the gin. Many module truck operators compensate for the shifting of the bed angle as a conventional module is loaded by starting with the chains significantly off the ground at the start of the load cycle. Because a module truck is picking up four individual entities instead of one continuous module, the bed deflection is less. The chains should be positioned just off the ground surface at the start of the loading cycle for round modules.

Do not run up front face of first round module up tight against the front of truck bed (headboard) for any reason. Stalling the travel of first module will cause cutting of the wrap due to relative motion of chains and will also close up gap to the next module. If modules are not staged properly, do not use the module truck as the means to correct incorrect staging.
