Abstract
In a method of making a carton tube (8) by winding a carton strip (3) with a layer of
glue (not shown) onto a mandrel (7),
the new feature is
that the carton strip (3) has previously been coated with a layer of glue of a kind, that can be changed from an inactive into an active state and vice versa, the glue being in the inactive state until passing through an activating unit (5) situated close to the winding-on point (9) (or even at these points or downstream of it, if thermal activation is used).
the new feature is
that the carton strip (3) has previously been coated with a layer of glue of a kind, that can be changed from an inactive into an active state and vice versa, the glue being in the inactive state until passing through an activating unit (5) situated close to the winding-on point (9) (or even at these points or downstream of it, if thermal activation is used).
By proceeding in this manner, spillage of glue on the equipment used for carrying
out the method is avoided, thus reducing the need for supervision.
Description
The present invention relates to a method of the kind set forth in the preamble of
claim 1.
US-patent specification No. 5,368,671 discloses a method of the kind referred to
above. In this known method, strips of sheet material are supplied to a machine, in
which a layer of glue is applied to the strips prior to winding the latter about a
suitable mandrel.
When making carton tubes in this manner, problems frequently arise due to surplus
glue being deposited on machine parts, such as scrapers or guides, eventually
preventing the machine from operating properly, unless care is taken to remove
glue thus having been deposited. In practice, this means that the operation of the
machine, with which the method is carried out, must be under constant or at least
frequent supervision by an operator.
It is the object of the present invention to provide a method of the kind referred to
above, with which it is possible to make carton tubes or similar articles in a process
not requiring constant supervision, and this object is achieved with a method of
said kind, according to the present invention exhibiting the features set forth in the
characterizing clause of claim 1. By proceeding in this manner, the process of
applying the glue to the sheet material can take place outside of the machine used
for winding the material into tubular bodies, so that no glue in a condition, in which
it can be deposited in an undesired manner on parts of the machine, will be
present in the latter. Preferably, the sheet material will be provided with a coat of
glue at some central location comprising specialized equipment for applying glue to
the sheet material and winding the latter with the glue in a non-tacky state into rolls.
These rolls can be stored until required for use in carrying out the method in a plant
for making carton tubes or similar articles.
The present invention also relates to
- an accumulation of sheet material for use in carrying out the method, set forth in claims 9 and 10,
- a machine for making carton tubes by carrying out the method, set forth in claim 11, and
- a tubular body being made by carrying out the method, set forth in claim 12.
In the following detailed part of the present description, the invention will be
explained in more detail with reference to the drawing, in which the principle of the
method according to the invention is illustrated using a bare minimum of
diagrammatically shown components.
The parts of and accessories to a machine according to the invention shown in the
drawing are
- a roll 1 rotatable about
- an
axis 2 so as to unwind - a
carton strip 3 passing through - braking, guiding and/or tensioning means 4, and further through
- an activating unit 5, from which it is helically wound whilst being driven by
- friction rollers 6, in turn driven by suitable means (not shown), about
- a stationary mandrel 7,
The carton strip 3 has previously been coated with a thin layer of glue of the type
that can be made to change from a non-tacky to a tacky state, the non-tacky state
being the state within the roll 1 and along the strip 3 as far as the activating unit 5.
When passing through the activating unit 5, the glue on the strip 3 is changed into
the tacky state, in which it remains until having been incorporated in the carton
tube 8. From that point, the process of removing the tube 8 from the mandrel 7
continues in any suitable manner.
The roll 1 is manufactured in much the same manner as known tape rolls with a
coat of glue in an inactive state, such as dry water-soluble glue, used e.g. for
closing and sealing cardboard boxes. This means that a supply of carton strip
without glue, e.g. a roll of carton strip as supplied by a manufacturer of such strip,
is placed in a suitable unwinding stand or the like, and then pulling the far end of
the strip through
- a glue-applying unit, in which a thin layer of glue of the activable type referred to above is applied to the strip, further through
- a glue-inactivating unit - in the case of water-soluble glue simply a drier capable of making the glue non-tacky, to end up in
- a suitable winding stand, in which the strip carrying the dried glue is wound to form a roll like the roll 1 shown.
In the exemplary embodiment shown, the activating unit 5 is placed at some
distance from the mandrel 7, but it may just as well be placed close to it, provided -
of course - that its activating function is not compromised. Thus, if a dried, water-soluble
glue is used on the strip 3, then it may be advantageous to have the
activating unit 5 at some distance from the mandrel 7 as shown, so as to give the
water being sprayed onto the strip 3 by suitable spray nozzles (not shown) in the
activating unit 5 time to penetate into the glue and make it tacky.
In the case of heat-activable glue, the activating unit 5 - in the form of a heat
source (not shown) - may be placed closer to the mandrel 7, even some distance
downstream from the winding-on point 9, i.e. down and to the right along the
mandrel 7.
In the exemplary embodiment shown, the strip 3 is wound helically about the
mandrel 7, the latter having a circular cross section allowing it to remain stationary.
The scope of the invention does, however, extend to processes differing from the
one illustrated. Thus, a strip may be wound in parallel layers on top of each other,
either on a round mandrel to form a short cylindrical tube, or on a rotating mandrel
having, say, a square, rectangular or other polygonal cross section, so as to form
the side walls in a box.
In the exemplary embodiment shown, a single strip 3 coated with glue on one side
is used for making the tube 8. The scope of the invention does, however, extend to
processes based on two or more strips, of which one or more may not have a coat
of glue, whereas one or more may have such a coat on both sides, so that the
strips are made to interleave in a suitable manner for forming e.g. a tube.
