Sticking to Business

For profitability's sake, web ends must be joined in a manner that minimizes scrap and maximizes material performance. Herbert explains that butt splicers, which are an absolute requirement for pressure-sensitive webs, must produce a splice with zero gap and no overlap. In lap splicing, he explains, the splicing mechanism is less complex, since it is only required to apply splicing tape on one side of the web, and keeping the tail short is desirable but not as critical as with a butt splice.
