Roving frame FT60 - FT70 - FT60D - FT70D

Description

• Up to 240 spindles (FT60 / FT60D); up to 192 spindles (FT70 / FT70D)
• Independent drives to reduce mechanical transmission, vibrations and friction
• Multi-motor spindles drive to increase transmission efficiency: 1 motor every 32 spindles (FT60 / FT60D); 1 motor every 24 spindles (FT70 / FT70D)
• Premium efficiency (IE3) motors for the spindles
• Multi-motor flyers drive to increase transmission efficiency: 1 motor every 32 flyers (FT60 / FT60D); 1 motor every 24 flyers (FT70 / FT70D)
• Timing belts for spindles and flyers to reduce maintenance and noise
• Electronic setting of main draft (option)
• Feeding creel with hexagonal rollers
• 3-over-3 or 4-over-4 drafting unit
• Weighting arm with pneumatic or spring load
• Diameter of the drafting rollers of either 32 mm or 27 mm for a better control of short fibers between front and middle roller
• Constant automatic adjustment of spindles speed to keep roving tension within the desired range
• Individual sensors to always guarantee an immediate stop of the machine in case of roving break (option)
• No suction required. Estimated saving: 4 kWh
• Bobbin tube diameter of 53.5 mm or 48 mm for a higher bobbin capacity
• Bobbin exchanger installable on either the head or the rear of the machine
• Perfect integration with Marzoli MTR and MTT bobbin transport solutions
• Connection with YarNet for production management
