Benefits of technology

"The present invention is about a device that prevents tape from falling off the edges of a tape package. It uses an idler roller that the tape passes through when unwinding. This roller causes the tape to go around the package at least once before being pulled through the rest of the dispensing system. This prevents the tape from falling off because it is pulled towards the center of the package by the preceding loop of tape. The use of the loop of tape also keeps the tape flat and prevents it from twisting further along the tape dispensing equipment. Overall, this invention ensures a smooth and safe unwinding process for the tape."

Problems solved by technology

Without that innovation, when the tape leaves the tape package at the moment the tape is at it's edge, the tape actually tries to find the shortest route, which is going off the side of the tape package; a defect called a fall-off.

Embodiment Construction

[0013] The present invention provides an improved apparatus for the dispensing of a tape at the corrugating machine or press. A tape package 13 is unwound, where the tape is wound with a traverse wind ratio as can be seen by the tape paths 14, 15 and 16 around the tape package 13. The tape 10 first leaves the nip point 17 and before going to the pulley 11 of the tape dispensing system, it goes around idler roller 12 and back around the tape package 13 idler roller 12 combination at least once, before going to the pulley 11.

Abstract

An apparatus to prevent the tape from falling off the edge of the tape package when unwinding.

Description

BACKGROUND OF THE INVENTION [0001] This invention relates to an improvement in an apparatus for dispensing a tape, i.e., ribbon, web or string, generally referred to herein as “tape”, when the tape is being unwound at a laminating machine such as a corrugating machine or press. One aspect of the present invention is to prevent the tape from falling off the edge of the tape package when unwinding. Another aspect is to prevent the tape from twisting in the dispensing equipment. [0002] Reinforcing or Tear tapes have been used for many years in modern packaging as an aid to maintain structural integrity or as an easy open feature in boxes, packages and / or containers. One limitation of the dispensing equipment used at the laminating machine is the difficulty to prevent the tape from falling off the edge of the tape package. To be able to put a reasonable amount of linear footage on a tape package, the use of a cross winding principle is mandatory, so for a tape with a width of ½ inch wid...
