Winding shaft and method for inserting a winding shaft into a winding device

Abstract

A winding shaft with a winding body and shaft journals that are positioned or situated at the ends of the winding body and are configured for insertion into a winding device. The winding body is composed of a winding sleeve that is open at the ends and the shaft journals each has an insertion section with clamping, with which they can be inserted into the end of the winding sleeve and detachably clamped to the winding sleeve, and together with it, constitute the winding shaft. This invention also discloses a method for inserting a winding shaft into a winding device.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to a winding shaft with a winding body and shaft journals that are positioned at the ends of the winding body and are configured for insertion into a winding device. This invention also relates to a method for inserting a winding shaft into a winding device, in which the winding shaft has a winding body and shaft journals that are positioned at the ends of the winding body, with which the winding shaft is inserted into corresponding recesses of the winding device.[0003]2. Discussion of Related Art[0004]Winding shafts for insertion into a winding device e.g. for winding web-like material such as webs of plastic film, fleece, and paper, are known and usually have a winding body equipped with winding journals at the ends of the winding body that are configured for insertion into the winding device and are held, for example, by corresponding winding arms of the device. In this connection, the winding ...

AI Technical Summary

Benefits of technology

The invention provides a winding shaft that is more flexible and adaptable for winding different materials. The shaft consists of a winding sleeve and shaft journals that can be easily detached and clamped onto the winding sleeve. This design allows for the winding of large parent rolls on a continuous winding sleeve without excessive weight or deflection. The winding sleeve is stable and made of metal or plastic, while the transition section between the shaft journal and the insertion section of the winding sleeue provides a stop for the winding sleeve and allows for different widths of the winding product. Overall, the invention provides a more efficient and flexible winding shaft for winding materials.

Problems solved by technology

Winding devices with laterally arranged mounts for continuous winding sleeves, however, usually cannot accommodate winding shafts, making them unsuitable for a multi-use winding.

In addition, when winding a narrow material web onto a winding device that is suitable for winding wide material webs, an unnecessarily wide winding sleeve must be kept on hand, which protrudes far beyond the finished winding and causes handling difficulties.
