Abstract
A web winding process is disclosed for controlling one or more characteristics of a web of material being wound into a roll. In one aspect, the system includes a weighing platform that weighs the roll of material as the roll of material is building. From this information, a basis weight characteristic of the web is determined. One or more parameters in the web making process can be controlled in order to ensure that the basis weight characteristic of the web of material stays within preset limits. In this manner, rolls of material can be produced having uniform characteristics and dimensional stability.
Claims21
A system for winding a web into a roll comprising:
- a rotatable reel spool for receiving and winding the web;
- a mounting device for receiving the reel spool, the reel spool being rotatably mounted on the mounting device, the mounting device being configured to permit the reel spool to move along a length of the mounting device as a roll of material on the reel spool grows in diameter;
- at least one weighing device in operative association with the mounting device, the at least one weighing device being configured to weigh the roll of material on the reel spool as the roll of material builds in diameter, wherein the at least one weighing device includes at least two four load cells spaced apart in a rectangular configuration;
- and
- a controller in communication with the at least one weighing device, wherein, based on information received from the at least one weighing device, the controller is configured to determine a basis weight characteristic of the web being wound on the reel spool.
A method for controlling a basis weight of a web of material comprising:
- producing the web of material in a web making process;
- winding the web of material on a reel spool to form a roll of material;
- monitoring a weight of the roll of material as a diameter of the roll increases;
- determining a basis weight characteristic of the web of material from the weight of the roll of material;
- and
- adjusting at least one parameter in the web making process based on the determined basis weight characteristic in order to maintain a basis weight of the web of material within preset limits, wherein the at least one parameter that is adjusted comprises an amount of fibers fed into the web making process.
