Abstract
A paste unit and method of glue metering therein for a bottom guide device for star seal bottom bags, which are formed from tube sections, for gluing of bottom warps or star seal bottom bags. The paste unit includes a glue reservoir, a metering roller connected with the glue reservoir, a glue application roller which may be connected to the glue reservoir and a making roller connected to the glue application roller which transfers glue from the application roller to the bottom warps or the star seal bottoms. Drive mechanisms assigned to the above listed rollers enable the circumference speed of the glue application roller and of the making roller to be adjusted independently of one another.
Claims11
A paste unit for a bottom guide device for gluing of bottom warps or star seal bottom bags, comprising:
- a glue reservoir;
- a metering roller connected with the glue reservoir;
- a glue application roller adjacent the metering roller;
- a making roller connected to the glue application roller which transfers glue from said glue application roller to the bottom warps or the star seal bottoms;
- and
- drive mechanisms assigned to said rollers, said drive mechanisms including drive motors for adjusting a circumference speed of said metering roller independently of said glue application roller and said making roller for controlling a glue application amount;
- said drive mechanisms being activated by a control device that adjusts, responsive to glue application amounts or changes in glue application amounts, circumference speeds of the metering, glue application and making rollers and aligns them to one another.
A method for controlling a glue application amount for a paste unit of a bottom guide device for gluing bottom warps or star seal bottoms and including a glue reservoir, a metering roller connected to the glue reservoir, a glue application roller which may be connected to the glue reservoir, and a making roller connected to the glue application roller which transfers glue from the glue application roller to the bottom warps or to the star seal bottoms, said method comprising:
- assigning drive mechanisms to the metering roller, the glue application roller and the making roller;
- and
- varying a ratio of circumference speeds of the glue application roller and the making roller for controlling the glue application amount.
A method for controlling a glue application amount for a paste unit of a bottom guide device for gluing bottom warps or star seal bottoms and including a glue reservoir, a metering roller connected to the glue reservoir, a glue application roller adjacent the glue reservoir, a making roller connected to the glue application roller which transfers glue from the glue application roller to the bottom warps or to the star seal bottoms, and drive mechanisms assigned to the rollers, said method comprising:
- adjusting a circumference speed of said metering roller independently of said glue application roller and said making roller such that a ratio of said metering roller circumference speed to a circumference speed of said glue application roller is varied for controlling a glue application amount.
