Benefits of technology

The patent is about an apparatus that can make pouches with water-soluble PVOH film and a better positioned printed pattern. It uses an apparatus that includes a first source of film, a second source of film, a source of composition, a pouch making unit, and a control system. The apparatus can make printed pouches that have a better position of the printed pattern, even if the PVOH film has challenging properties. The technical effect is to provide a more precise and reliable method for making printed pouches with a better position of the printed pattern.

Problems solved by technology

Due to the physical and chemical properties of film comprising PVOH, obtaining the correct position of the printed pattern onto the pouch may be challenging.
Indeed, when a pouch is created in the pouch making unit, maintaining the registration or phasing of the to printed pattern with the pouch can be complicated.
An undesired distortion of the shape of the pattern on the pouch may be observed if registration is not achieved.
When the printed pattern is printed via several printing stations, the adjustment of the different parts of the pattern may also be difficult.

Embodiment Construction

The Apparatus

[0014]As shown on FIG. 1, the apparatus (1) comprises a first source of film (21) and a second source of film (22). The apparatus (1) may comprise a roll (21) of film to be printed. The film (11) comprises a copolymer of polyvinylalcohol. The film may be unwound from a spindle or a reel. The apparatus may comprise a film unwinder (31). The apparatus may comprise an automatic splicer (41). The apparatus may comprise an accumulator / dancer system (51) for control of the unwind tension and speed. The tension and / or the metering velocity may be controlled on the in-feed of the printing unit by utilizing an in-feed driven roller (61) which may or may not be coupled with tension measurement load cells. The apparatus may comprise a film pre-treatment station (70). The film pre-treatment station may provide corona treatment for increased spreadability and / or deposition of the compound to be printed (e.g. dye or ink). The apparatus may comprise an endless rotating system such as ...

Abstract

Apparatus for producing pouches including a source of printed water-soluble PVOH film, a second source of film, a source of composition, a pouch making unit comprising a filing system to form pouches from the first film, the second film, and the composition, a control system for monitoring and adjusting the position of the pattern onto the pouches. Pouches made by the apparatus.

Description

FIELD OF THE INVENTION[0001]The present invention relates to the field of apparatus for producing pouches comprising a water-soluble film of polyvinyl alcohol (PVOH) resin, a pattern being printed on the film, and a composition at least partially enclosed into the film. The present invention also concerns pouches produced with the apparatus.BACKGROUND OF THE INVENTION[0002]It is desired to prepare pouches comprising a water-soluble film comprising PVOH with a printed pattern thereon. Due to the physical and chemical properties of film comprising PVOH, obtaining the correct position of the printed pattern onto the pouch may be challenging. Indeed, when a pouch is created in the pouch making unit, maintaining the registration or phasing of the to printed pattern with the pouch can be complicated. An undesired distortion of the shape of the pattern on the pouch may be observed if registration is not achieved. When the printed pattern is printed via several printing stations, the adjust...
