Abstract: The present disclosure relates to methods and apparatuses for rejecting defective absorbent articles from a converting line. At a downstream portion of a converting process, a continuous length of absorbent articles may be subjected to a final knife and cut to create discrete absorbent articles advancing on a first carrier. From the first carrier, the discrete absorbent articles may be transferred to a transfer apparatus, which in turn, transfers the discrete absorbent articles to a second carrier. The transfer apparatus may include carrier members that orbit around an axis of rotation and may be adapted to receive the absorbent articles from the first carrier and transfer the absorbent articles to the second carrier. Defective absorbent articles may be detected by an inspection system, which may be operably connected with the transfer apparatus and/or the first carrier to remove the defective absorbent articles from the converting process.

Abstract: Method for manufacturing discrete articles from a material web using a cyclic master reference signal to synchronize the servo actuation of multiple operational units in a manufacturing apparatus to perform periodic operations on successive product segments of the material web and thereby form the articles, without the need for ongoing external phasing or registration to maintain synchronization of the operational units relative to the articles being made. The method is particularly suited for application in the manufacture of disposable absorbent articles and other products formed from web materials. Because of the coordination by a common reference signal, the execution by each of the individual servo systems of its programmed actuation instructions results in its actuation being synchronous with that of the other servo systems.

Abstract: A feed mechanism sheet material sequentially on demand to a take-up mechanism of processing machinery. The feed mechanism has a feed table with a gate. Sheets may be stacked against the gate, which allows only the lowermost sheet to pass therebeneath. Rollers within the surface of the rotatably driven to advance the lowermost sheet beneath the gate to the take-up mechanism. A restraining device prevents freewheeling over run of the rollers. The sheets may be longer in length than the circumference of a tool-carrying roll set used to process the sheet. The difference is accommodated by transferring sheet feed through the nip between the tool set and a separate servo-controlled drive upstream of the nip.

Abstract: A bag maker-packaging machine adapted for use with formers having different sizes uses pull-down belts to pull by suction an elongated film which has been tubularly formed by a former. When a new former is installed, the pull-down belts are moved from specified belt reference positions towards the surface of the film in a tubular form, and the distance travelled by them until they come into contact with the film surface is measured. After the size of the former is thus identified, positions of some of the components such as a guide roller and a turn bar for the transportation of film to the former are adjusted accordingly. Data corresponding to different former sizes may be stored in a memory and compared with the identified size of the former currently installed. The user can see on a display device what kinds of product can be packaged by using this identified former and may also be informed if the memory does not store any data for formers of the identified size.
