Winding Material Utilization via Braking Counterforce
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for unwinding and processing winding materials result in residual material left on storage drums, which is economically disadvantageous, especially for high-quality materials, as they do not effectively maintain constant tensile force post-unwinding, leading to incomplete integration into further processing.
Innovation Solution
A method where a counterforce is generated by a braking device after unwinding, using a connecting material of inferior quality attached to the storage drum to maintain constant tensile force until the winding material is fully processed, with a braking device arranged at the entry point of the processing machine to ensure controlled braking and integration of the entire material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If the stock drum is positioned close to the downstream processing machine to minimize residual material, then material utilization is improved, but the technological gap required for preparatory treatment is insufficient
Solution Approach 1:
A connecting material is introduced as an intermediary element between the winding material and the stock drum. This connecting material serves as a mediator that allows the stock drum to be positioned at the optimal distance for preparatory treatment while ensuring complete utilization of the winding material through controlled braking action.
2Ease of manufacture
If the stock drum is positioned far from the downstream processing machine to allow preparatory treatment, then material treatment capability is improved, but residual material increases
Solution Approach 1:
The braking device is activated in advance to generate counterforce before the winding material is completely unwound. This preliminary action ensures that the connecting material is fully drawn into the downstream processing machine, eliminating residual material while maintaining the necessary technological gap for preparatory treatment.
Solution Approach 2:
The system monitors the unwinding process and activates the braking device based on the position of the winding material. This feedback mechanism ensures optimal timing of the braking action, allowing complete material utilization while maintaining adequate technological gap for preparatory treatment.
3Loss of substance
If a braking device is introduced to generate counterforce and maintain constant tensile force, then material utilization is improved, but device complexity increases
Solution Approach 1:
The braking device is designed to automatically activate and deactivate based on the unwinding process state. The system self-regulates the braking force to maintain constant tensile force without requiring complex external control mechanisms, thereby minimizing device complexity while achieving complete material utilization.

AI summary
The invention relates to a method and a device for the optimal utilization of the winding material (1) during the winding and/or unwinding of stock drums in conjunction with feeding to winding machines. The winding material can be a textile web, a woven web, a wire, or the like. Starting from the currently unused remaining portions of the winding material generated during further processing, the object of the invention is to provide a method and a device for carrying out the method, enabling the inclusion of the entire winding material (1) from the stock drums (2) in the subsequent technological processing.This problem is solved by maintaining, according to the developed method, the counterforce required to keep the tensile force acting on the winding material (1) constant until the winding material to be fed is completely incorporated into the subsequent processing step. Advantageously, the counterforce is maintained by a coilable connecting element (3) that is connected to the winding material and to the supply drum (2) and is of a lower quality than the winding material. According to the developed device, means that generate and controllable counterforces are used to counteract the tensile force, thereby maintaining the counterforce opposing the tensile force until the winding material (1) is completely drawn into the subsequent processing device.Preferably, the device is designed such that a coilable connecting element (3), corresponding at most to the length of the distance between the supply drum (2) and the entry point into the winding machine, is detachably connected at its first end to the supply drum (2) and at its second end to the beginning of the material to be wound (1).
