The present disclosure relates to systems and processes for inspecting and evaluating qualities of printed regions on substrates, wherein the systems and methods may be configured to eliminate subjective aspects relating to human involvement in performing visual checks when evaluating print quality. The systems may include one or more communication networks connecting one or more sensors with an analyzer. In operation, ink is applied to a substrate to create at least one printed region, and the sensors are configured to inspect the printed region. The sensors may be configured to communicate measurements and/or images to the analyzer. And the analyzer may then calculate one or more quality subscores based on respective measurements and/or images. In turn, a full print quality score may be calculated based on one or more of the quality subscores. The analyzer may then execute a control action based on the full print quality score.

A sensor system for detecting a property of or within an absorbent article. The system may comprise a first sensor and a first transmitter. The sensor may be disposed in or on the absorbent article. The sensor may have a first status and may be capable of changing to a second status. The first transmitter may be capable of sensing a change in status of the sensor from the first status to the second status. The first transmitter may be capable of checking the status of the sensor noncontinuously. The first transmitter may programmed to check the status of the first sensor at least every 5 minutes but not longer than every 2 hours.

A transport unit includes: a transporting device that turns a pad 90 degrees while the pad rotates from a receiving position to a transfer position; and first and second receiving rollers that sandwich a sheet and an absorbent body between a holding surface and the respective receiving rollers at the transfer position. The holding surface includes first and second sloped surfaces that are aligned along a pad rotating shaft which extends at the transfer position. The first and second receiving rollers have outer diameters decreasing from proximal ends to distal ends and are disposed such that the distal ends are positioned on sides of first and second ends of the holding surface, respectively. The first and second receiving rollers are disposed so as to sandwich the sheet and the absorbent body between the first and second sloped surfaces and the first and second receiving rollers, respectively.

The present disclosure relates to taped and pant articles comprising substantially identical chassis.

The present disclosure relates to systems and processes for detecting and rejecting defective absorbent articles from a converting line. In particular, the systems and methods may utilize feedback from technologies, such as vision systems, sensors, remote input and output stations, and controllers with synchronized embedded clocks to accurately correlate inspection results and measurements from an absorbent article converting process. As such, the systems and methods may accurately apply the use of precision clock synchronization for both instrumentation and control system devices on a non-deterministic communications network. In turn, the clock synchronized control and instrumentation network may be used to control a reject system on converters of absorbent articles. In some embodiments, the controller will reject only defective absorbent articles without the need to reject non-defective absorbent articles.

The present disclosure relates to systems and processes for controlling the relative positions or phasing of advancing substrates and/or components in absorbent article converting lines. The systems and methods may utilize feedback from technologies, such as vision systems, sensors, remote input and output stations, and controllers with synchronized embedded clocks to accurately correlate component placement detections and placement control on an absorbent article converting process. The systems and methods may accurately apply the use of precision clock synchronization for both instrumentation and control system devices on a non-deterministic communications network. In turn, the clock synchronized control and instrumentation network may be used to control the substrate position. As such, the controller may be programmed to the relative positions of substrates and components along the converting line without having to account for undeterminable delays.

A system for cutting a web material and applying the web material on a substrate. The system comprises a feed roll configured to advance a web material. The system includes an anvil roll configured to receive the web material from the feed roll and provide a section of web material having a defined length. The system includes a cutting element configured to cut the web material to form the section of web material. The anvil roll is configured such that the anvil roll surface advances at an anvil roll surface speed. The feed roll is configured to rotate at a first feed roll surface speed that is slower than the anvil roll surface speed and a second feed roll surface speed that is substantially the same as the anvil roll surface speed when the cutting element cuts the web material.
