Abstract
Apparatus and method for controlling the winding of a sheet of material such as paper and film finished consumer products into a log using an adjustable reference profile. The apparatus and method may provide improved process control, product quality, manufacturing production rate and/or process repeatability. The apparatus and method provide more consistent finished log properties by measuring at least one process parameter during the manufacturing process. The process parameter is then correlated with the desired finished product characteristics and an appropriate correction is made to the reference profile.
Claims19
A method of using a winding apparatus to wind a sheet of material onto a core to form a log, comprising the steps of:
- winding the sheet of material about the core in accordance with a reference profile;
- measuring a process parameter to obtain at least one process parameter measurement;
- providing a reference profile adjustment according to the at least one process parameter measurement;
- and
- adjusting the reference profile according to the reference profile adjustment,
- the core having a rotational velocity change of at least about 400 revolutions per minute between about 2 and about 35 machine degrees.
A winding apparatus for winding a sheet of material to meet a reference profile, the apparatus comprising:
- a mandrel with a removable core disposed about the mandrel,
- a material handling system for delivering the sheet of material to the core;
- a drive system for rotating the mandrel and core, the drive system winding the sheet of material onto the core to form a log, the core having a rotational velocity change of at least about 400 revolutions per minute between about 2 and about 35 machine degrees;
- at least one process parameter measuring device to obtain at least one process parameter measurement, the at least one process parameter measurement being used to calculate a reference profile adjustment, the reference profile adjustment being used to modify the reference profile.
