Abstract

A paste unit (3) for a bottom guide device for star seal bottom bags, which are formed of tube sections, is introduced. The paste unit (3) serves for the glueing of bottom warps, or star seal bottom bags. The unit's characteristics are a glue reservoir (1), or a glue source (5), a metering roller (2), a glue application roller (3), as well as a making roller (4). Drive means are assigned to the rollers. Innovating and inventive is the fact that the glue (9) is transferred to the printing roller (4) by the glue application roller (3). This closed system provides the advantage that the glue (9) is applied evenly, and that the metering can be adjusted at a very fine setting. Furthermore, no glue (9) can be discharged to the environment of the paste unit.
