Abstract
An apparatus for affixing glue strips to both the top and bottom sides of folded, yet-to-be assembled cardboard containers. The apparatus, which is loaded prior to use with a wide roll of release coated paper, slices it into two strips. Each strip is then cut into many short strips of the desired length and glue applied to these short strips just prior to their being placed on folded containers. The release coated paper than forms a protective cover for the glue until the containers are used. The use of the release coated paper not only is much cheaper than pre-glued paper but also eliminates problems associated with storing and handling narrow pre-glued paper strips.
Claims9
A machine for placing glue strips on folded cardboard containers as the containers travel through the machine, the machine being fed by at least one wide roll of release coated paper during use, comprising:
- (a) means for slicing the wide roll of paper into at least two narrower strips of paper;
- (b) mean for handling each strip of paper as it is being fed through the machine in such a manner as to reduce the stress on the strip;
- (c) means for cutting individual segments of a desired length from one end of each strip the strips;
- and
- (d) an injector for putting a layer of glue on each segment just prior to its placement on one of the folded cardboard containers.
A machine for placing glue strips on folded cardboard containers as the container travel through the machine, the machine being fed by at least one wide roll of release coated paper during use, comprising:
- (a) a means of slicing the release coated paper;
- (b) a mean of handling each strip of paper as it being fed through the machine in such a manner as to reduce the stress on the strip, the handling means including an elongated chamber in which an elongated loop of the paper strip is gently tensioned by a vacuum;
- (c) means of cutting the strips into individual segments of a desired length from one end of the strip, the cutting means comprising a knife and a final drive pulley wheel, the knife dropping on the strip in such a way as to form a tangent to the final drive pulley wheel, the knife having a blade with a serrated edge in order to lower the stress on the strip;.
- (d) means for applying a layer a layer of glue to each segment, the glue applying means including a glue nozzle and means for holding each segment on the outer periphery of the wheel while the glue nozzle makes intermittent contact with the segment.
