Solution Overview
Problem
Existing winding devices for web-shaped materials face challenges in efficiently threading and winding materials with varying web paths, requiring significant manual effort and complicating the attachment process to a core and rollers.
Innovation Solution
A winding device with a movable throw-on element and a guidance system comprising fixed and movable guidance sections, ensuring a rectilinear connection between the throw-on element and the rotational axis, allowing for flexible web paths and reducing manual effort by automating the threading and winding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed guidance system is used for webbing-up, then the structure is simple and stable, but the web path cannot be varied and manual threading effort increases
Solution Approach 1:
The guidance system incorporates movable guidance sections that can be dynamically adjusted to create different web paths. The throw-on element can move between a retracted position (for threading) and an extended position (for winding), allowing the system to adapt its geometry without becoming overly complex. This dynamic capability enables web path variability while maintaining structural simplicity through controlled movement rather than multiple fixed components.
2Ease of operation
If manual threading is used, then the device structure is simple, but operator effort and time consumption increase
Solution Approach 1:
The webbing-up assembly automatically performs preliminary threading actions by moving along the guidance system's web path. The throw-on element is pre-positioned and automatically extends to guide the web onto the roll, eliminating the need for manual threading operations. This automated preliminary action significantly reduces both operator effort and threading time.
3Extent of automation
If the throw-on element is made movable to enable webbing-up, then the threading function is improved, but the structural complexity and potential reliability issues increase
Solution Approach 1:
The throw-on element is segmented into distinct functional portions: a fixed mounting section and a movable extension section. This segmentation allows the critical throwing function to be isolated in a simple, reliable mechanism while the movable portion handles the adaptive positioning. The segmented design reduces complexity and potential failure points compared to a fully movable throw-on mechanism.

AI summary
A winding device for a web-shaped material has at least one first frame and at least one first roller holding device, with at least one roller holding assembly which can rotate about a first rotational axis. The winding has device at least one pressing element, and the at least one pressing element is arranged to be movable relative to the first frame in at least one adjustment direction and opposite that at least one adjustment direction. The at least one adjustment direction has at least one component which points towards the first rotational axis. A guide system for at least one drawing device, for drawing at least one material web, is arranged such that a first guide section of the guide system is arranged in a stationary manner relative to the at least one first frame. At least one linear connection between the at least one pressing element and the first rotational axis always intersects a second guide section of the guide system, regardless of the position of the at least one pressing element. A method for drawing a material web into a winding device is also provided.
