We're only a retailer, but we work closely with different tape converters who supply us with the products we sell on FindTape.com. We often get asked what exactly does an adhesive tape converter do? Basically a tape converter uses various processes to modify adhesive tape products that they get from tape manufacturers. These processes include slitting, rewinding, die-cutting, printing, laminating, etc. They convert (change) master rolls of tape (similar to large rolls of carpet or newsprint in size) to usable sizes and forms for customers. For instance typically gaffers tape comes in a 56" x 900 yard jumbo roll and then individual rolls are converted from that source material into industry standard sizes such as 48mm x 55m on a rewind slitter that cuts the tape as it pulls it off the source roll and then winds it back up on smaller cardboard cores. Other products may be custom cut on lathes that are more flexible when different widths are required. Tape manufacturers also convert their own tape; but often times it is more economical for a specialized converter to do the work for them (also tape manufacturers typically have very high minimums for rolls cut to non-standard widths).
