Model-based control of lateral web behavior - An interconnection of two web guiding systems within packaging machinery
(Oklahoma State University, 2015-06)
Within packaging industry mostly web materials are used to form bags or similar shaped packages. In order to professionally convert these materials and achieving increasing quality requirements of bags, detailed knowledge ...
Modeling web behaviour in printing press and in printed electronics
(Oklahoma State University, 2013-06)
VTT together with several companies in the printing value chain have studied web handling through the printing press. Studies have focused on the web tension formation mechanisms in printing which have an effect e.g. on ...
Ke models: Theoretical dynamic subsystems of longitudinal web strain
(Oklahoma State University, 2011-06)
Efficient design and optimization of many production processes often require models which predict transient and steady state web strains. To date, much attention has been given to modeling web strains much less than unity. ...
Fully R2R gravure printed smart tags and related web handling challenges
(Oklahoma State University, 2013-06)
Although a smart tag which can communicate with a smart phone via NFC (Near Field Communication) has been considered as a core tool for bringing up the ubiquitous society, the difficulties in integrating 13.56 MHz RFID ...
Comparison of multi-span lateral dynamics models
(Oklahoma State University, 2015-06)
It's obvious that when a web changes its lateral position at a roller, subsequent spans will be affected. Less obvious, is the fact that transient stress variations will also affect downstream spans. Multi-span models are ...
Roller nip deflections
(Oklahoma State University, 2017-06)
Rubber covered nip rollers are used in many web handling and processing applications. Successful use of these systems requires an accurate knowledge of the impact of various design and process parameters on key response ...
Predicting the web length and layers in a wound roll
(Oklahoma State University, 2019-06)
The length of web in a wound roll is one mark of roll quality. The available web length in a roll is a concern for many who process webs and those who convert webs. There are algorithms that estimate the length of web and ...
Measurement of web curl
(Oklahoma State University, 2017-06)
Generally it is desirable for web based products to have a flat planar shape. Unfortunately coated and laminated products often assume a curved shape. This is a defect commonly called "Curl". The first step in solving most ...
Boundary conditions for lateral deformation of webs transiting rollers in roll-to-roll process machines
(Oklahoma State University, 2017-06)
The lateral deformations of webs in roll-to-roll (R2R) process machines can affect the quality of the manufacturing process. The lateral registration of the web in successive R2R processes can determine whether a product ...
Tin-canning defects in thin film winding
(Oklahoma State University, 2015-06)
