Beaming unit fixed to the main structure, which moves along the reel axis to guarantee the perfect alignment of the beam during winding; this system excludes any additional installation cost
Aluminium winding reel, base diameter 950 mm, fixed cone
Width 1300 mm, inclination 11°, mounted on the main structure of the machine and controlled in rotating and moving phases by interpolation of x and z axes
Digital control receives and processes all necessary data; the calculator memorizes up to 6 parameters of progress and repeats them for the next sections avoiding any possible surmount
Warping and beaming speed are kept constant automatically, considering the diameter increasing (determined by computer)
Meters-counter incorporated in the computer arrests the warper at the prefixed section’s length, as well as arrests the beam’s rotation when the winding is finished with the inserted arrest alarm
Braking System
Reel’s braking system of new generation has 2 big size disks (diameter 850 mm – thickness 40 mm) in spheroidal cast iron, which permit a long braking efficiency in the most difficult working situations
Braking system is controlled by two separate circuits:
During warping the immediate arrest of the reel is guaranteed by 2 pliers commanded by oil
During beaming the tension of yarn is kept constant by 1 or 2 pneumatic pliers, on the base of the tension programmed by the computer
Such system permits to have a wide range of braking, making as beams with less yarn and low tension, as beams with more yarn and high tension
Speeds
Warping speed up to 800 m/min
Beaming speed up to 300 m/min
Braking For Beaming
Partial up to 7500 nm
Reduced up to 3000 nm
Installed Power
Reel motor 22 kw ac (inverter)
Beam motor 34 kw ac (inverter)
Beam shifting motor 0.75 kw ac (brushless)
Reed shifting motor 0.5 kw ac (brushless)
Computer’s Special Functions
Setting of working cycles:
Cycle 1: winding on reel
Setting of total real meters to wind
Setting of the initial step
Marking of patch at wanted number of meters with programmed arrest
Pre-arrest for sortings
Memorizing of yarns missed at breaking (commands)
Winding speed
Braking setting and adjustment
Winded meters constantly displayed
More warps overlap setting
The corrections of progress are made automatically controlling the winded thickness
This operation can be repeated for 5 times more and after the first section is set, all other sections are prepared with the same progress scales
Cycle 2: winding on beam
Constant speed setting
Automatic stops at points memorized during the warping phase
Jig insertion or exclusion
Braking setting and adjustment with possibility of range selection
Possibility of more warps on the same beam
Possibility of clockwise and anticlockwise rotation of the beam (slow march) also in warping phase
Motorized Reed Trolley With Automatic Sorting
Strong structure completed with guides for vertical movement of the lease reed
Separating bars at the entrance of the reed trolley, mounted on a special motorized device, permit to separate different levels of the creel and to create an oscillating up/down movement of yarns in correspondence of the lease reed
The oscillating movement of the separating bars increases the duration of the reed and avoids the frequent yarn breaking due to the teeth consumption
Automatic motorized leasing device with reed for 368 passages mounted on the vertical shifting guides, controlled by self-braking gearmotor permits the positioning of the reed on the following positions:
High position (high sorting)
Central position (working)
Low position (low sorting)
Waxing Device
For liquid paraffin, width 4800 mm, completed with:
Stainless steel tank
Stainless steel waxing cylinder
Stainless steel command cylinder
0.75 hp pick up and delivery pump with exhaust valve
Variator with differential
Level adjustment for pump’s control
Motorized Beaming Unit
Beam-holding spindles with beam raising and lowering device
Motorized beam-holding supports to consent the beam-centering and to favour the operations of beam alignment with the yarn coming from the reel
Movable Creel With Rotating Panels
For 352 positions on 8 levels with 44 positions on each level – 22 for each side in 3 spans on 12 panels
Vertical gauge: 320 mm
Horizontal gauge: 320 mm
Rotating bobbin-holding panels on the external sides, supported on the rotating axis by 2 supports completed with bearings
Rotating panels arresting device to permit the correct orientation of the bobbin-holders towards the tensioners
320 tensioners for rotating panels creel + 32 with continuous feeding, with centralized adjustment of the working tension, mod. hz, commanded by the digital control, completed with triple passages with sintered bushings and yarn-braking disks mounted on motorized self-cleaning devices
The tensioners are synchronized with the arrest of the warper in order to optimize the increase of the yarn tension
The reference value for the yarn tension is set and visualized on the creel digital control display
Yarn passing vane with sintered bushings
Electric warp stopping control at yarn-breaking or at the end of the bobbin
Creel Sizes
Height 3050 mm
Width max 3400 / 4770 mm
Length 8500 mm
Additional Equipment
Antiloop device between the bobbin and the tensioner
Gearmotor for transversal translation controlled from the warper
