GENERAL INFORMATION
• AMF Stringline for the production of 3,375 of 19 oz. strings of
dough up to 26” long
• Infeed Synchronizing Conveyor
• Pressure Board/Moulding Section (C/W Flour Duster)
• Proofer Section (C/W Flour Duster and Two Exhaust Fans)
• Servo-Drive Centering Device
• Three Stages Moulding Section (C/W Two Dough Extenders)
• Liftable Club Roll Cutting Section
• Transfer Conveyor
Synchronizing Conveyor
• For proper timing of the dough
balls into the moulder
(controlled by photo eye)
• Double eliminator logic
• Constructed of formed stainless
steel with UHMW side wedges
• Powered by a hollow shaft gear
brake motor
Moulder Section
• Stainless steel frame
• Air operated lifting device permits:
-Rapid change over of dough guides
-Easier access for sanitation and maintenance purposes
• Flour sifter
• Pneumatic pressure board
Common Drive
• Proofer drive is protected by an electronic over torque
meter against catastrophic damage
Proofer
• 4.5 min. of proofing time at 3,375 pieces per hour
• Stainless steel tubular construction
• Stainless steel paneling
• Upper horizontal section with sliding plexi glass panels
• Teflon® coated and pneumatically controlled dropping
gates with separate timing values
• Adjustable flour duster located above the double dropping gates
• Proofer trays are made of rolled aluminum, plastic end brackets,
and sandblasted to a coarse finish
• Proofer chain is 40 mm extended pitch over size rollers
• Over sized hub sprockets
• Horizontal sections of the proofer have angle iron chain guides
and rails to tilt to one side (this helps to reduce sticking in the trays)
• Strings are transferred from the trays to the discharge conveyor
without dropping
• Discharge conveyor is stainless steel construction and is driven
from by the proofer chain
Centering Device
• To bring the string of dough back to the center of the moulding conveyor
• Built on a stainless steel frame with an aluminum based plate
• Conveyor section is built from stainless
steel side plates with an adjustable UHMW
bed for proper tensioning of the stainless
steel balanced weave mesh conveyor belt
• Driven by a flange mount gear motor
using a belt drive system
• Centering is accomplished by a multi
element infra red light beam source
and receiver, processor, servo controller,
and linear actuator
Three Stages Moulding Section
• String moulding section consists of a moulding conveyor with two
powered extender pressure boards made up of two conveyors at 90
degrees to the moulding conveyor
• Extender pressure boards have rough top conveyor belt and travel to the
outside of the moulding conveyor very slowly causing the dough string
to extend with very little stress. In addition there is a standard pressure
board with universal side guides
• Moulding conveyor is constructed of
stainless steel with an adjustable speed
gear motor
• Adjustable infeed roller for tracking
• (2) two pressure boards supplied with the
stringline. One pressure board is for
final moulding of strings to full length.
The second pressure board has a slot in
the middle, where a stationary knife is
located to split long strings into two rounded end loaves
Club Roll Cutting Section
• Cut blunt end rolls and transport the elongated strings to the next step
in the process
• Constructed of stainless steel and a flat top Intralox conveyor belt
• Driven by a fixed speed gear motor
• Stainless steel side panels
• Rotary timing flaps at the infeed end
to keep the string straight and evenly
spaced from each other
• Flaps are driven from a gear motor and
controlled from a signal from the
common drive
• Slip clutch on the flaps to prevent injury
• Machine comes with one set of cutting
devices with 4 knives
• Cutting device is constructed of stainless steel
Transfer Conveyor
• To transfer the loaves or rolls from the Club Roll Cutter
next step in the process
• Inverter controlled
• Pneumatic Teflon coated infeed flaps
• Powered transfer roller to ease the transfer of the loaf between
two conveyors
MECHANICAL FEATURES
• Allen Bradley PanelView 1000 keypad operator interface witch displays:
-Status messages
-Alarm messages
-System Start/Stop buttons
-Flour sifters Start/Stop buttons
-Fans Start/Stop buttons
-Fans speed control
• NEMA 12 electrical enclosure (painted steel) including:
-Alarm reset, master relay control, emergency stop
-Main disconnect switch
-Allen Bradley 5/03 PLC
-Allen Bradley PanelView 1000 monochrome keypad
-Allen Bradley AC inverters
-Allen Bradley Ultra 3000 servo amplifier
-Convenience plug to allow programming without
having to open panel door
• Nema 12 stainless steel electrical panel
• Allen Bradley PanelView 1000 color
• Spare parts kit
MECHANICAL OPTIONS
• Optional de-gassing roller: if needed, an optional de-gassing roller can be supplied with separate drive and two
Teflon® lined rollers, 4 inches in diameter. The distance between the rollers is adjustable with a hand wheel.
The rollers have adjustable speed. They are located just after the centering device on the long moulding
station. In that case the overall length of the long moulding station is increased by 24 inches
