SAFETY:   Carriage movement is driven by a chain or belt. Belt control ensures greater safety (parachute system).

Belt:  If the belt should break, there will be activated a mechanism against fall, carriage will be intercept. When carriage moves down and hit something, then he will lift himself a little and stay down on the subject.   

Chain: The carriage has a bottom plate connected with the sensor. When carriage moves down and the sheet touches something (leg, shoulder,whatever), the switch will be activated and carriage begins to move up.

                                 C0   -    Mechanical brake - core tension of roll (basic stretching)

 Fromm wrapping machines - carriage C0
    • The carriage enables to stretch the film; pre-stretching the film is not possible
    • Tension 0-50 % depends on the quality of the film
    • The film is stretched between the carriage and the pallet, controlled by a lever or wheel and braking of the top / bottom.
    • The brake is installed at the bottom of the carriage
    • The carriage is especially suitable for use for customers with small film consumer; core: Ø 76 mm; film thickness: 9-35 my or so called pre-stretched film 
    • Suitable for medium to high pallet weights: 150 to 2.000 kg
    • A photoelectric cell for automatic pallet height detection
    • The speed controlled by a frequency converter
    • The film overlap can be controlled by a frequency converter
    • Quick replacement of film rolls                                                                                                       Datasheet
 Fromm wrapping machines - carriage C0, description

Description of stretching: Stretch is adjusted by turning the knob (1) which presses against the pin (2), inserted into the high-quality brake block (3). There is a spring (4) in the brake block to absorb possible wear during the working process. The complete stretch can be released by moving the handle (5) to the down position. This carriage can be used to wrap with thin film or pre-stretch film 250-500 mm wide.

Safety: The carriage is mounted in such a way that it can be lifted from its position. The foot protection sensor is not available. The distance between the floor and the top of the carriage is approx. 115 mm. 

                          C1 -  Mechanical brake - roll tension (stretching over auxiliary rollers – tensioning rollers) 

  Fromm wrapping machines - Carriage C1  
    • A strong rigid steel structure
    • The film is stretched over the roller
    • The stretching force can be set using the wheel and locked using the lever
    • Stretch 20-50 % , depending on the quality of the film
    • The stretch of the film is uniform
    • The overlap of the film can be controlled by a frequency converter
    • A photoelectric cell for automatic pallet height detection
    • Easy to replace the film; release the brake for changing the core
    • The speed controlled by a frequency converter
    • Safety foot protection according to CE
    • Low maintenance of the braking system

                      C2 -  Mechanical brake - rolles pre-stretch

     Fromm wrapping machines - Carriage C2          
    • Strong rigid steel structure
    • The film is stretched over the roller
    • Prestretch 0 to 80 % , depending on the quality of the film
    • The stretching force can be set using the hand wheel and locked using the lever
    • The stretch can be set during motion
    • The speed controlled by a frequency converter
    • The stretch of the film is uniform
    • The overlap of the film can be controlled by a frequency converter
    • A photoelectric cell for the automatic pallet height detection
    • Easy and quick to change the film; release the brake to change the core
    • Suitable for medium to high pallet weights: 150-2.000 kg
    • Max. pallet height: 2.000 mm
    • Safety food protection according to CE
    • Low maintenance of the braking system
    • Suitable to use in combination with 12/15/17/20/23/30 and 35 micron LLDPE stretch film

                C4 - Electromagnetic brake (stretching over the roller – tensioning roller)

 Fromm wrapping machines - Carriage C4
    • The film carriage with an electromagnetic brake
    • The film is pre-stretched between the film carriage and the pallet
    • The pre-stretch is adjustable by means of touch buttons on the control panel
    • For tension up to 100%
    • Stretch can be set manually -> smoother setting
    • The stretch of the film is uniform
    • The stretch of the film is set using a potentiometer; it allows a high stretch
    • Recommended to work with all kinds- of stretch-film
    • Including protective safety protections and door with a switch

                        C6  - One motor pre-stretch system

Fromm wrapping machines - Crriage C6  
    • Pre-stretch ratio fixed by gears 150% / 200% / 250% / 300%
    • End-user can only change the pre-stretch by changing gears
    • Dancer roller, for film feed, controlled by return spring 
    • Tension control in direction of the pallet
    • The film roll can be replaced very quickly and easily within seconds
    • Carriage belt drive, with parachute safety system
    • High pre-stretch reduces the consumption of the film. This will enable you to achieve the best results at the lowest possible costs and with optimum pallet stabilization and goods protection
    • Photoeletric cell for dark object and dark film
    • This ensures optimum reliability in combination with an economic advantage

                       C7  -   Two motor pre-stretch system 

 Fromm wrapping machines - Carriage C7  
    • Pre-stretch ratio by two motors from 100% to 400%; (Steps of 10%)
    • End-user can change the pre-stretch on the OP3
    • Programming of different pre-stretch during carriage movement up and down
    • End-user can only change the pre-stretch by changing gears
    • Dancer roller, for film feed, controlled by return spring and / or lead cell
    • Tension control in direction of the pallet
    • The film roll can be replaced very quickly and easily within seconds
    • Carriage belt drive, with parachute safety system
    • High pre-stretch reduces the consumption of the film. This will enable you to achieve the best results at the lowest possible costs and with optimum pallet stabilization and goods protection
    • Photoeletric cell for dark object and dark film
    • This ensures optimum reliability in combination with an economic advantage
    • Also in case that the pallets are large, extremely lightweight, or have sharp edges, FS390 with C7 can be set so that even if film of average quality is used, there is no tear or breaking
