Banding Machine Tape Handling Assembly for Adhesive Paper Tape
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing banding machines using stretch film are inadequate for objects requiring adhesive properties or aesthetic considerations, as they are not suitable for less elastic materials like paper tape and face challenges with printing that remains undistorted post-stretching.
Innovation Solution
A banding machine designed to accommodate less elastic materials, such as one-sided adhesive tape, which self-adheres to objects and allows for precise application and cutting, using a tape handling assembly with rollers, wipers, a brake, and a knife to ensure secure and aesthetically pleasing banding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If stretch film is used for banding, then the film can elastically stretch and contract to hold the product, but the film cannot positively adhere to the object and printing becomes distorted
Solution Approach 1:
The patent changes the material parameter from elastic stretch film to inelastic paper tape, which eliminates the stretching and contracting behavior that causes printing distortion. The paper tape maintains its dimensional stability while providing adhesive properties through the one-sided adhesive application, thereby resolving both the adhesive strength and printing precision requirements.
Solution Approach 2:
The invention uses a composite structure combining paper substrate with adhesive material applied to one side. This composite material provides both the structural integrity needed for precise printing and the adhesive properties for positive attachment to the object, overcoming the limitations of pure stretch film.
2Ease of operation
If stretch film banding is used, then the band can encircle the product, but it is inappropriate for objects requiring aesthetic appearance or enhanced integrity
Solution Approach 1:
The patent changes the elasticity parameter from high (stretch film) to low (paper tape), making the material suitable for applications requiring aesthetic appearance and enhanced object integrity. The inelastic nature of paper tape provides a clean, professional appearance while the adhesive properties ensure reliable attachment that enhances rather than compromises object integrity.
3Reliability
If one-sided adhesive tape is used, then the tape can self-adhere to the product, but the tape handling requires precise control mechanisms
Solution Approach 1:
The one-sided adhesive tape applies the principle of self-service by self-adhering to the product upon application. The adhesive side automatically bonds to the object surface without requiring additional fastening mechanisms, simplifying the overall system while maintaining reliable adhesive bonding.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables secure and aesthetically appealing banding of objects using less elastic materials, with improved adhesive properties and ease of printing, addressing the limitations of stretch film banding machines.
Implementation Method 1
The use of one-sided adhesive tape, i.e., tape having adhesive applied to one side of the tape along its length, is particularly contemplated, as such tape will self-adhere to the product and/or to itself.

AI summary
A banding machine applies bands about objects for packaging, decorative, or other purposes. An object is banded with tape by: grasping a starting end of a tape extending from a tape roll between a first roller and a brake, with the first roller being situated adjacent the object alongside a second roller; orbiting the object with tape roll to apply the tape to the circumference of the object; during the orbit, pressing the starting end of the tape against the object with a wiper, and releasing the tape starting end from the brake; upon the tape's orbital approach of the tape starting end, receiving the tape over the first and second rollers; extending a knife between the first and second rollers to cut the tape, thereby defining a finishing end of the tape extending about the object; and pressing the finishing end of the tape against the object with a wiper.
