Methods for manufacturing printed laminates

Methods for manufacturing printed laminates or elastic printed laminates are disclosed. The printed laminates may have a first extensible material and a second extensible material. The first extensible material may have a plurality of repeating graphic sets each having a repeating graphic set length. The first extensible material may have a first strain and the second extensible material may have a second, different strain. The second strain may be constant. The first strain may be variable to correspond to the repeating graphic set lengths to a predetermined laminate pitch. The first and second extensible material may be joined together at a point of joinder. An elastic member, such as a plurality of elastic strands, for example, may be positioned intermediate the first and second extensible materials to form an elastic laminate.

Systems for unwinding a roll of thermoplastic material interleaved with a porous material, and related methods

An apparatus (un-interleaver) for unwinding a roll of material interleaved with another material, and for separating the materials, includes a first platform, a second platform, a tension-sensor, an edge-sensor, and a controller. The controller monitors signals generated by the tension sensor and the edge sensor, and in response to the signals: a) causes the speed at which the second platform rotates to change to maintain a predetermined tension in the second material as the second material travels from the first platform toward the second platform, and b) causes the second platform to move relative to the first platform to align the edge of the second material traveling toward the roll of second material with the edge of the second material in the roll.

Base material processing apparatus and detection method

A base material processing apparatus includes first and second edge sensors and a displacement amount calculation part. The first edge sensor acquires a first detection result (R1) by detecting the position of an edge of a base material in a width direction at a first detection position. The second edge sensor acquires a second detection result (R2) by detecting the position of the edge of the base material at a second detection position. The displacement amount calculation part calculates the amount of displacement in the position of the base material in the transport direction or the amount of difference in the transporting speed of the base material on the basis of the first and second detection results (R1, R2). Thus, the amount of displacement in the position or the amount of difference in the transporting speed can be detected without depending on images such as register marks.

Web medium orientation detection

In a method for high speed printing of web-based media, a medium is pulled along a media transport path to a pulling transport mechanism. The orientation of the medium with respect to the media transport path is sensed and this orientation is compared to a reference orientation to detect an orientation error. If an orientation error is detected, one or more of the following steps is performed: adjusting a print job for an image to be printed on the web medium; adjusting the transport speed; emitting a communication signal; and stopping the pulling transport mechanism and the image forming unit. It is the insight of the inventor that productivity may be increased by allowing a tight winding printing system to start printing at relatively high speed and reduce this speed only when significantly large deviations in the orientation of the web are detected.
