Abstract:
Due to rapid advancement in computing technology of both hardware and software, the labor intensive sewing process has been transformed into a technology-intensive automated process. During an automated process, product materials may become wrinkled or folded, which can slow down the automated process or result in human intervention. Various examples are provided related to the automation of sewing robots, and removal of wrinkles from products. Images of material on a work table can be captured and analyzed to determine if there are wrinkles or folds in the product. The robot can remove the wrinkle or fold by manipulating the material through the use of end effectors such as, e.g., budgers.
Abstract:
The present invention relates to a method of guiding a web with a shifting path of the web to a substantially constant centration point. It comprises the steps of providing a web with a shifting path of the web from a source of the web, measuring upstream of said centration point, the position and/or orientation of said web by a sensor arrangement, and guiding said web to said centration point in accordance to the measurement results. The present invention advantageously relates to operations in the manufacturing of absorbent articles such as unwinding web rolls that are wound in a shifted manner, in particular spirally wound web rolls, and removing web from containers of loose web material. The invention also relates to a device for the execution of the method.
Abstract:
on coupe le film étirable à la sortie de la bobine de grande largeur (1) pour réaliser des laizes (L) de largeurs et de nombres correspondants aux bobines souhaitées, on étire les laizes (L) provoquant un écartement des lignes de coupe suite à la diminution de la largeur desdites laizes (L) résultant de l'étirement, on relâche la tension d'étirement de chacune des laizes (L), on enroule, à l'état relâché, les laizes (L) sur des mandarins (2) pour réaliser les bobines de petites largeurs (11).
Abstract:
Methods, devices, apparatus, and assemblies for converting fanfold material into packaging templates are disclosed. A converting system includes a converting machine that performs various conversion functions on the fanfold material. An infeed guide system directs the fanfold material from one or more stacks into the converting machine without folding, creasing, or otherwise compromising the fanfold material. The infeed guide system includes infeed guides with substantially S-shaped segments. The infeed guide system also includes a frame structure that substantially maintains the curvature of the substantially S-shaped segments within a desired range to prevent damage to or jamming of the fanfold material in the infeed guide system.
Abstract:
Bahnspreizvorrichtung, mittels der in einer Bahnbearbeitungsmaschine nebeneinander geförderte Bahnstränge quer zu ihrer Förderrichtung voneinander abspreizbar sind, die Bahnspreizvorrichtung umfassend: a) Schneideinrichtungen (4) zum Längsschneiden einer Bahn (P) wenigstens in einen linken, rechten und mittleren Bahnstrang (T1, T2, T3), b) eine linke Umlenkeinrichtung (51, 61, 71) mit linken Umlenkachsen für den linken Bahnstrang (T1), c) eine rechte Umlenkeinrichtung (5r, 6r, 7r) mit rechten Umlenkachsen für den rechten Bahnstrang (T3), d) und eine mittlere Umlenkeinrichtung (5m, 6m, 7m; 23a-c) mit mittleren Umlenkachsen für den mittleren Bahnstrang (T2), e) wobei die Umlenkachsen von wenigstens zwei der Umlenkeinrichtungen relativ zu der Förderrichtung (F) des jeweils zugeordneten Bahnstrangs (T1, T3) und relativ zu der Förderrichtung des noch verbleibenden weiteren Bahnstrangs (T2) je solch eine Neigung aufweisen, dass die zugeordneten Bahnstränge (T1, T3) parallel voneinander und von dem weiteren Bahnstrang (T2) abspreizbar sind.
