Benefits of technology

The present invention provides a winding device that allows for easy winding of a web of material onto a core. The device includes a spool with a shaft and a sleeve that can rotate relative to the shaft. The spool has gripping members that engage the core to allow the web to be wound onto the core. The gripping members disengage the core to allow for easy removal of the wound material. The device also includes a sensor and a controller that monitors the speed of the spool and adjusts the speed of the web to ensure a smooth winding process. Overall, the invention simplifies the winding process and improves efficiency.

Problems solved by technology

Existing winding devices for this purpose are not as efficient or convenient as would otherwise be desired.

Embodiment Construction

[0028]FIG. 1 illustrates a system 10 for inflating, sealing, and winding a web 12 of material into a roll 14. Roll 14 is shown in phantom for clarity. System 10 generally includes an inflation and sealing apparatus 16 and a winding device 18. The inflation / sealing apparatus 16 may be any suitable device for producing a web, e.g., of inflated cushioning material, as described, e.g., in U.S. Pat. No. 7,220,476 or in U.S. Publication No. US 2010-0251665 A1, the disclosures of which are hereby incorporated herein by reference thereto. As further described in the foregoing references and illustrated in FIG. 9, the web 12 produced by apparatus 16 may be an inflated cushioning material 20. Inflated cushioning material 20 may be formed from two superposed film sheets 19, and may include rows of inflated chambers 22, wherein each of the chambers 22 has at least one change in width over their length, e.g., with two inflatable sections of relatively large width 24 connected by relatively narro...

Abstract

A winding device generally includes a spool, which includes a shaft, a sleeve rotatably coupled to the shaft such that the sleeve and the shaft are capable of partial independent rotation relative to one another, with the sleeve adapted to receive thereon a core onto which a web of material may be wound, and one or more gripping members, which are adapted to engage the core upon relative rotation of the shaft in a first direction, and disengage the core upon relative rotation of the shaft in a second direction.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a winding device for winding a web of material onto a core and, more particularly, to an improved winding device for webs comprising inflated cushioning material.[0002]Various machines for forming inflated cushioning material are known, which produce inflated cushioning from a web of un-inflated material by inflating and sealing closed gas-containing chambers within the material. Such cushioning is used to package items, by wrapping the items in the cushions and placing the wrapped items in a shipping carton, or simply placing one or more inflated cushions inside of a shipping carton along with an item to be shipped. The cushions protect the packaged item by absorbing impacts that may otherwise be fully transmitted to the packaged item during transit, and also restrict movement of the packaged item within the carton to further reduce the likelihood of damage to the item. At the same time, the end-user can inflate and ...
