The BOW Model 632 provides an instrumentation, audio and video tape cleaner with precision wind for 1-inch and 2-inch NAB and 1/2-inch NAB or IBM reels. The BOW Model 632 was designed to handle reel sizes from 10.5-inches to 16-inches in diameter. With the industries' latest electronics and tape path available, the Model 632 is the solution to your tape conditioning needs.  

With the optional optical inspector the user can establish a fail-criteria to weed out bad tapes and save valuable reusable tapes. Perfect for conditioning old tapes for archives, restoration, or to ready the tape for media transfer. The optical inspector information can also be sent to a printer, located in the base of the unit, giving the user a hard copy of the results.  

The BOW Model 632 guides that tape gently through the tape path and cleaning stations at a programmed tension that allows for the best packing of the tape. Constant tension can also be selected as desired. The four constantly advancing tissue cleaning stations clean both sides of the tape both before and after the sapphire cleaning blade, which can be removed from the tape path as required. Alternate speeds are also available for handling tapes with extreme stiction issues.  

The 632 is available in both our standard cabinet (as shown) or ready for rack mounting to a 19 inch EIA rack.

For the best magnetic tape winder/packer/cleaner for your valuable tapes, the BOW Model 632 is the most reliable, gentle handling, and best value in the industry.

Stop Distance Select - Stops tape at selected distance. Typically used to run enough tape from larger reel, for example a 14-inch, to fit on a 10.5-inch reel. Also, tape can be stopped at a known defective section for splicing.


Optical Inspector with Defect Counter - In-line quality control device that opto-electronically scans the entire surface of the tape, detecting physical abnormities (pin holes, damaged or folded edges, stretched tape, nicks, oxide voids, etc.). Allows user to grade tape based on physical defects found and also dropout information from the recorder.


Optical Inspector with Defect Counter with Printer - 800 Option with Printer for printout of physical defect locations
