2.1 MACHINE DESCRIPTION
Thismachine,whichoperates with a continuous workcycle, is designed toform liners madeof thermoplastic material
inside caps.
The work cycle begins with the plastic material coming out of the extruder. A plastic pellet of a pre-determined size
is then cut and placed inside the cap. The liner is then formed by the movement of a mechanical system and the
resulting product is checked for quality.
The main parts of the machine are indicated in the illustration below.
Themachine can beequippedwith a visionsystemfor inspecting thetop (crown skirt +liner) and bottom (decoration)
of the caps.
Detailed instructions regarding the vision system are found in the relevant manual.

2.1.1 MAIN MACHINE ASSEMBLIES
2.1.1.1 Extruder
This unit is used to melt the granular material and force it out of a suitably sized port at the required temperature. The
sizeoftheoutletdependsonthetypeofplasticcompoundbeinghandled.Theequipmentonthedrumcutstheextruded
material into pellets and places them in the caps.
The unit features a plasticization section consisting of a barrel (1), auger (2), a number of electric heating elements
(3)(locatedin 5 different zones) andfour cooling fans(4). The unit is rigidlysecured to agearbox &thrust bearing unit
(5) and the drive unit (6) which rest on a slide (7) capable of moving backwards and forwards to allow for expansion
of the plasticization unit. When the mounting bolts, which secure it to the machine base are removed, the unit and
extruder can be moved sideways, making it easier to carry out maintenance.
The extrusion head (8) and nozzle (9), that the molten material flows out from, as well as the bypass valve (10), used
to discharge the material through an auxiliary outlet port, are located in the front part.
The mount (11) holds up the front part of the extruder. It is provided with a lock that secures the extruder to its base
after adjustments have been made.
The hopper (12), that feeds the granular material to the extruder, completes the unit.

MAIN FEATURES 2
2.1.1.2 Insertion drum
This unit is used to cut the extruded plastic material into small pellets and place them in the caps. The drum comes
equipped with spindles (1). Cutters (2), which cut the plastic into pellets and place them in the caps, are attached to
the bottom of the spindles. The spindles are seated in cylindrical holes equally spaced apart around the periphery of
the drum (3). The cams (4), located at the top, move the spindles up and down. While the drum is rotating, the cutters
move near the extrusion nozzle so that the plastic material can be cut into suitably sized pellets. The cutter holds the
pellets, brings them down to the caps and puts them in. This vertical movement is performed thanks to the cams
provided.
Thesizeandshapeofthecuttersiscloselyrelatedtothetype oftheplastic materialused.This isnormallydetermined
during machine commissioning.
After the cutter has nearly come into contact with the bottom of the cap, the pellet is pushed against the bottom by a
plunger. The plunger is located in the middle of the cutter. The latter moves vertically as it is secured to a cam outside
the drum in the pellet insertion area.
As a result, plunger operation is different and independent from that of the cutter it is secured to.
Compressed air is blown while the cutters are moving away from the bottom of the cap to help detach the pellets.

2.1.1.4 Forming unit
This assembly is used to form the liners inside the caps by compressing the pellets.
The upper part of the drum houses the fixed forming plungers (2). The lower part contains the spindles that hold the
caps (1). The latter move vertically. The caps are placed on the lower spindles (1) by the transfer turntable. While the
forming drum rotates, the lower spindles are raised by a cam (3) bringing the hot pellet against the forming plungers
(2) thereby forming the liners.
The profile of the liner depends on the shape of the forming tools installed.

Thisunitchecksthelinerstoseewhethertheyhavebeenproperlyformedandthattheshellshavenotbeendamaged.
The unit incorporates sensing spindles (1) located in cylindrical bores equally spaced apart around the periphery of
the body (2). Sensors (3) are secured to the bottom of the spindles while the spindles are attached to a cam (4) on
the top. The cam moves the spindles up and down.
While the unit rotates, the sensors are moved down and come into contact with the caps, checking them for any
defects. A mechanical and vacuum-operated system is employed for this purpose.
Any defective caps and/or lines are rejected when they are on the exit conveyor belt by an air blower.
