Automatic Truck Tires Buffi ng Machine designed to minimize process time, cut labor, and increase consistency in buff texture. This special automatic
configuration reduces and footprint and expense from two machines. While the buffing tire on the first chuck, the operator can load and unload the tire from the second chuck: One operator, Twice the production.

Vertical buffing head and 3 axis movement
Dual expandable hubs
Dual belt detector and circumference measure
Embedded operating system
Automation components Rockwell
Buffs 15” to 24.5” tires
Buffs the widest super singles
Unlimited number of programs
Equipped with electric safety mats and light curtains
Adjustable tire rotation speed
PC with touch screen

One operator - Twice the production, lowest cost per buff (30 tph)
Reduced footprint from two machines
Belt depth monitoring and circumference measuring
Less dependent on operator skill
Consistent undertread using adjustable buff-to-zero-technology
Reduced expense from two machines
Efficient rubber dust removal and less maintenance required

EAGLE TRUCK 2500 buffer is a fully automatic machine, suitable for both cold and hot retreading, designed to remove the residual tread from truck, bus and light transport vehicle tire casings with a high level of precision. The machine can simultaneously perform both the buffing of the tread and the brushing of the sidewalls following a symmetric or asymmetric programmed profile.

Vertical buffing head and real 3 axis movement
Buffing profile up to 4 radii
Hanging buffing unit for easier cleaning
Machine structure with arch frame to give solidity and precision in the process
Automatic cycle joystick operator for manual operation
Automatic blade-wear compensation
Automatic program to invert rotation of buffing head and brushes
Automatic tire lifting system for bead positioning
Control of total and partial production, both number of
Belt detector cycles and type of programs performed
Circumference measuring device
Webcam and modem connection for online technical assistance
Unlimited program capacity
Adjustable tire rotation speed (chuck driven on the axis)
Automation components Rockwell
PC with touch screen, display showing the actual circumference of the buffed tire

Builder developed for the cold retreading industry and designed to apply pre-cured tread strips on truck, bus and light transport vehicle tyre casings. It is equipped with a support for application of calendered cushion gum and an automatic rotating knife to cut the pre-cured tread strips. The machine can be tread roll lifting system provided.

For tires from 15” to 24”, including 445/65R22,5”
Automatic stitching cycle (Radial stitching)
Limit switch for automatic tread length control
Foot pedal that controls tire rotation in both directions for manual cushion gum application
Expandable chuck unit driven centrally with gearbox motor
Rotating knife integrated in the machine
Crank for poly removal
Full tread rolls lifting system
Automation components Rockwell

FOR CUSHION GUM APPLICATION

Automatic extruder machine developed for the tire retreading industry and designed to fit the extruded cushion gum in strips on the tire casings to be retreaded. The machine is able to carry out the following operations:

Inflation of the tire on the hydraulically expanded mandrel
Automatic detection of the buffed profile before the application of the cushion gum.
Application of the cushion gum in strips with the consequent skiving filling (up to a maximum hole size 20x2mm)
Tire deflation at end of cycle. These operations don’t need the presence of the operator.

Manual pressure tyre tester for inspection under pressure of truck tIres. The test is performed at 3 pressures, and 2 speeds can be set for the rotation of the tIre.

Test steps at 2, 6 and 8 bar
8 bar test step limited to 10 seconds
Adjustable tire speed (2 speeds)
Pedal for tire rotation inversion
For tires 15” ÷ 24.5”
