Abstract

PURPOSE:To tie an article with tape without carrying it off from a straight line by feeding two shrinkable tapes to the straight conveying line from above and below, tying the article with these tapes sealed together at their front ends, sealing the rear ends and cutting off the sealed rear end thereof at its central part. CONSTITUTION:Containers A, when placed on carry-in conveyors 5a and 5b, are fed between an upper and lower tape 9 and 10 sealed together at their ends by a heater 23 on a sealer 21. These tapes 9 and 10 are thereafter sealed widthwise by the sealer 21. The container A around which such tapes are wrapped into an annular form is sent to the next process with the tapes connected with each other, whereby the sealed part is cut off. The sealed part remaining on the tape side from the cut-off position at the nearly central portion of the rear seal part serves as a forward sealing part for binding the succeeding article. Therefore, this method permits a series of articles fed onto a straight conveying line to be bound successively into the form of a strap without requiring manual operations, leading to the reduction of the man-hour.
