double-sixteen folder

A particular folding machine capable of folding two 16page sections or one 32-page section. This folder can also be equipped to produce two 32-page sections, though of a smaller page size. Double 16s have three folding levels and four sets of folding rollers. The sheet is slit in half at the first folding level and each half is folded individually at right angles at the second level. It is folded once again at the third level, which has only one set of folding rollers; in this level, if the sections are to be outserts, each of the two folded sheets is folded in succession, whereas if the sections are inserts, both sheets are combined and folded together. A fourth folding level may be added to make the machine capable of producing two 32page sections. See also:FOLDING MACHINES . (320 )
