The “Roto-Drive” 505A
Automatic Cable Measuring System
Motorizes Cut to Length Operations

This unique cable measuring unit accepts cable up to 7/8" O.D.
Shown here with the PT-501X Pay-Off Table and the GC-575 Guillotine

The operation of the Roto-Drive is extremely simple. A push button in front of the machine lifts the upper roller to allow the introduction of the cable. A trim cut is made when used in conjunction with a cut-off unit and the electronic counter is set to the length (and number of pieces wanted with the RD-505A). The ‘start’ push button or foot switch is depressed and “presto” the Roto-Drive dispenses and feeds the cable to a cut-off unit at 24" per second. The cycle repeats until the number of pieces wanted is reached. (RD-505A)

A prescaler adjustment allows the counter to be calibrated to the exact measured cable length. Because of this feature, the Roto-Drive dispenses the exact amount of cable wanted eliminating costly rejects and rework. Accessories are available such as motorized pay-off with dancer for heavy coils or when cut to length dimensions tolerances exceed normal specifications.

TECHNICAL DATA

• The Roto-Drive RD-505A was designed to be maintenance free; ball bearings or self-lubricated bronze bushings are used throughout.
• The driving rollers are air cushioned-pressurized and are covered with a polyurethane compound for toughness and long life. The upper and lower rollers are both driving rollers to eliminate slippage and are synchronized with a unique “lubrication free” timing belt system.
• The Roto-Drive uses a sophisticated solid state drive and control system. It also features an electronic counter with large LCD. display for setting the length of the cable, which can be adjusted from 6" to 99999.9" in increments of .100". The batch counter stops the machine automatically when the preset number of pieces is reached; a totalizer is built in the counter.
• The highest quality components have been selected to provide trouble free operation in excess of 5 million cycles.
• No lubrication is required except for the pneumatic air supply. Controls are provided to synchronize the Roto-Drive with accessories.
• The Roto-Drive dimensions are 8"W x 15 1/2"H x 24" and at 95 lbs. this unit is easily movable. Power required is 110 V.A.C. single phase, 4 amps. Capacity: 7/8" max. Measured accuracy: within 1% for jacketed cables.
• +- 1% for Greenfield and armored cables. (when convolution play is 1/2" per ft., max.) We recommend the use of a motorized pay-off unit with dancer when heavy reels are used or when cut to length tolerances are beyond normal specifications.

RD-505A Cable Measuring system components

• PT-501X: Pay-off turntable with an automatic brake.  Accepts standard 250 ft. cable coils, capacity is 150 lbs. max. dimensions are 24" x 24" x 18" high. Different hat sections (coil core dimension) can be provided as well as a centering hub for cable coiled on a reel.
• PT-525: Heavy duty payoff table with an automatic brake and a capacity of 250 lbs.
• RB-502: receiving bin constructed of heavy steel. Dim. are 30" x 30" x 30H on casters, 500 lbs. capacity.
• PT-525: heavy duty pay-off table using a steel machine base with thrust ball bearings and air actuated brake with a capacity of 500 lbs.
• GA-555: guide arm to feed cable to the RD-505A
• CM-380: control box needed to use the RD-505A with the AV-525 or GC-575
• TB-505: Heavy duty 60 X 30 steel table with predrilled holes to mount the components of the cut to length system. 
• JC-530: jib crane equipped with an electric hoist to lift and load the cable coils on the pay-off table. This device eliminates manual lifting of the coils and promotes safety.
• TT-535: is a heavy-duty turntable designed to receive a pallet of cable coils. This unit can be used in conjunction with Jib-Crane JC-530.
• MD-540: motorized reeler-dereeler when used with coils over 250lbs
• PD-545: is a variable speed dereeler with dancer to feed cable smoothly into Roto-Drive. Call for specifications.
• GC-575: Pneumatic guillotine cutter for aluminum or light gage steel cables up to 15/16” Dia.  Enclosed cutting blade for safety.
• AV-525: Cut-off band saw for the RD-505 system, cuts up to 1" diameter cable
