Embodiment Construction

[0019] Referring to the aforementioned figure 1, the membrane 1 is made of a relatively very resistant plastic material and is tightly bonded or bonded to a relatively less resistant membrane 2 . It is important that there is a difference in strength between the two films that results in a difference in their percent elongation under traction and / or a difference in their thermal expansion, and / or a difference in their thermal shrinkage. In this regard, from a strictly conceptual point of view, the manufacturing machinery or equipment 4 must be equipped so that the strip 3 formed by the joining together of the two films 1, 2 emerges therefrom, having a straight line such as that shown in FIG. linearity resulting from proper thermal or dynamic conditions. An example of these conditions could be a mechanical pulling force that exceeds the reaction force that would cause the ribbon to curl; another example of these conditions could be keeping the ribbon at a lower temperature so t...

Abstract

The invention provides a belt (3) for bundling and decoration. The characteristics of the belt include: preferably two layers of polyolefin plastic flat films stacked separately, which are bonded or glued together to form a tight A united body that includes base films having elastic extension properties and / or thermal shrinkage properties that differ from each other, such that upon leaving the production equipment, the differences between the films result in a difference between the two films. The difference in the degree of shortening between the layers causes their constituent materials to curl, and the curling is included in the range of elastic deformation, and this range is consistent with the normal way in which a tape composed of said layers is stretched on a normal reel (10). The winding-related curvatures are consistent so that the tape (11) is produced, which spontaneously curls when unrolled from the reel (10) at the ambient temperature in which the tape is used.

Description

technical field [0001] The present invention generally relates to a decorative strap commonly used in binding and trimming, which tends to curl. The invention also relates to a method of forming said strip. Background technique [0002] In gift giving, it is known to use decorative tapes to secure wrapping materials, such wrapping materials comprising paper or other decorative film-like materials. To make the packaging more attractive, curls or spiral wraps are formed at the ends or other portions of the various knotted decorative strips to increase the attractiveness. [0003] This crimping is usually done manually by sliding the band firmly against the sharp edge of any tool, usually the edge of a pair of scissors. Belts that are most suitable for crimping are made of one or more layers of suitable materials and / or mixtures thereof. The most commonly used materials include plastic materials belonging to the expanded or non-expanded polyolefin family. The main materials...
