Definitions

  • the invention relates to a method for producing a cover or the like with at least one cover adjoining a cover spine, a hot-melt adhesive being applied to the inside of the cover spine and having been brought into a liquid or at least pasty state by prior heating.
  • the invention further relates to a device for performing this method and a cover of the aforementioned type.
  • Covers of the above type usually consist of a cover spine and fold-bound cover covers on the front and back. They are usually made of cardboard, and the front cover can also be made of a transparent plastic. Covers of this type are described for example in DE-PS 25 28 225 and DE-OS 22 37 583.
  • a hot melt adhesive is applied to the inside of the back cover.
  • Such hot melt adhesives are solid at room temperature, but - depending on their composition - become liquid at temperatures between 70 ° C and 190 ° C. After cooling, the hot melt adhesive returns to the solid state, this process being repeatable several times.
  • the above properties of the hot melt adhesive are used when binding paper sheets in such a cover.
  • the paper sheets are placed in the cover with their longitudinal edges perpendicular to the still hot melt adhesive and the cover is then brought into a binding device, as is known for example from DE-OS 27 43 685.
  • the cover then stands with its back on a heating plate that heats the hot melt adhesive through the back of the cover. After transition to the liquid state, the paper sheets penetrate into the hot melt adhesive so that their edges are enclosed by the hot melt adhesive. After cooling, the paper sheets are firmly connected to the back of the cover.
  • the covers described above come onto the market with the hot melt adhesive attached to the back of the cover.
  • two methods are known for applying the hot melt adhesive to the inside of the back cover.
  • the hot-melt adhesive is applied to the back of the cover in a liquid, that is to say heated, state using an adhesive application head which is connected to a storage container and a pump is connected (see. DE-OS 26 11 242; DE-OS 29 37 171).
  • This form of application has the advantage that raw material in granular form can be used for the hot melt adhesive, which is relatively cheap.
  • the hot melt adhesive applied in this way has a caterpillar shape, ie it is thicker towards the center than at the sides. The consequence of this is that, when later binding, the outer and therefore the most stressed paper sheets are kept in a too thin layer of hot-melt adhesive and are therefore easily detached. If, in addition, only a small number of sheets of paper are bound in relation to the width of the cover spine, the sheets of paper can slide outwards before the hot melt adhesive is heated, or at least tilt unevenly, which is also undesirable.
  • the hot-melt adhesive is placed in the form of a solid strip on the back of the cover and glued to it under the action of pressure and heat or using an additional adhesive.
  • This can be done by hand or by a method as described in DE-OS 30 10 642.
  • a hot melt adhesive strip previously cut from rolls or sheets is placed between two flexible strips that stand up on a base at a suitable distance from one another, then the cover is brought over such that its back is above the hot melt adhesive strip, and the cover is then pressed using a press stamp or a press roller against the bending strips and the hot-melt adhesive strip.
  • a press stamp or a press roller against the bending strips and the hot-melt adhesive strip.
  • the invention is therefore based on the object of designing a method for applying a hot-melt adhesive to a cover so that an exactly positioned hot-melt adhesive application which is uniform over length and width and has a desired cross section can be produced at the lowest possible cost. Another object is to find a device suitable for carrying out this method and a cover with a particularly favorable shape for the hot-melt adhesive application.
  • the first object is achieved in that the hot melt adhesive is introduced into a mold open on one of the long sides in the heated state, the cover is placed with the inside of the cover spine over the open side of the mold and the cover spine is pressed onto or into this mold.
  • the hot melt adhesive In the case of a narrow hot melt adhesive application, it may be sufficient if the hot melt adhesive is kept in shape only on its long sides, that is to say the end faces are open. Due to the then low hot melt adhesive entry, correct dosing can prevent the hot melt adhesive from flowing beyond the intended dimension at the end faces. To this extent, however, the procedure can be more precise, in particular when the hotmelt adhesive is applied more broadly, if the hotmelt adhesive is also given a shape on the end faces of the mold.
  • the hot-melt adhesive is heated to a temperature which is so far below the normal processing temperature before it is introduced into the mold that the hot-melt adhesive is in a state which is comparatively viscous compared to the fully liquid state at normal processing temperature.
  • the temperature of the hot melt adhesive when it is introduced into the mold should be 40% to 80%, preferably 60% of the normal processing temperature at which the hot melt adhesive is fully liquid, the aim being that the hot melt adhesive is only heated to the extent that it is suitable for its processing is just sufficiently viscous.
  • the invention further provides that when the binding spine is pressed into the mold, folds are formed on both longitudinal sides at the same time, so that the application of the hot melt adhesive and the formation of the folds can take place in one work step.
  • the device for carrying out the above-described method is formed by a mold formed by a base and side walls and open on one of the long sides, by a pressing device for pressing the spine of the cover into the open long side of the mold, by a heating device for liquefying the hot melt adhesive and by a feed device for the filling of the liquid hot melt adhesive marked in the mold.
  • a mold formed by a base and side walls and open on one of the long sides
  • a pressing device for pressing the spine of the cover into the open long side of the mold by a heating device for liquefying the hot melt adhesive and by a feed device for the filling of the liquid hot melt adhesive marked in the mold.
  • the side walls on the long sides of the mold are expediently designed as bending edges for embossing folds when the binding spine is pressed into the mold, as a result of which two work processes can be combined with one another.
  • the pressing device has a pressing die which is movable relative to the open long side of the mold.
  • the press ram should expediently be provided on its working side with an elastic layer so that, on the one hand, the best possible sealing is achieved at the edges of the mold and, on the other hand, the press ram can adapt to the amount of hot melt adhesive filled in.
  • a good seal is further supported if the upper edges of the side walls of the mold are assigned corresponding grooves in the working side of the press ram.
  • the hot melt adhesive can be given practically any desired cross section by appropriate formation of the From. It is advantageous to give the shape in the region of the central longitudinal axis a lower height than on the long sides.
  • a particularly preferred embodiment of a cover which cannot be produced by the known methods, can be produced by the device described above if the bottom of the cover is arched up in the shape of an arch. In this way, the hot melt adhesive application receives a trough-shaped depression on the side on which the paper sheet edges come to be when binding, which brings the paper sheets together towards the center and also holds them together.
  • the hot melt adhesive is thickest at the long edges, where the paper sheets are exposed to particularly high loads, which improves the hold of the paper sheets. Ultimately, this opens up the possibility of working with small hot melt adhesive thicknesses, i.e. saving hot melt adhesive.
  • the bottom of the mold be mounted interchangeably in order to enable different cross-sectional shapes and thicknesses if required. Furthermore, it may be expedient to arrange the bottom of the mold so that it can move towards and away from the open side.
  • the mold and feed device for introducing the hot melt adhesive are movable relative to one another.
  • the feed device can be arranged in a stationary manner.
  • the inner walls of the mold expediently consist of a non-ground steel alloy, since it has been found that the hot-melt adhesive can then be easily removed from the mold. This can also be supported by cooling the mold and / or by using a release agent which is added to the mold before the hot-melt adhesive is introduced.
  • the invention furthermore relates to a cover of the type mentioned at the outset, in which the hot-melt adhesive application is made thinner in the region of the central longitudinal axis than on its longitudinal edges, an arc-shaped depression to the central longitudinal axis being particularly advantageous.
  • a cross-section is favorable for hot-melt adhesive application, because then on the long side edges, where the paper sheets are exposed to particularly high loads, the most hot-melt adhesive is available for holding the paper sheets and also the paper sheets are brought together towards the center and be held together. This greatly reduces the error rate when binding the paper sheets.
  • GB-A-20 72 096 shows a cover whose hot-melt adhesive strip has a concave curvature on the free surface according to the drawing.
  • this curvature and its possible purpose were not considered. Rather, the U-shaped design of the spine is emphasized, which leads to the fact that the hot melt adhesive entry adheres to the side legs of the spine. Because of this special feature, this cover also does not pose the problem of improved hold of paper sheets in the edge region of the hot melt adhesive entry, which is the case with covers of the present type with hot melt adhesive application that is free from the back of the cover.
  • the device 1 shown schematically in FIG. 1 has a plate 2 which can only be seen here in part.
  • the plate 2 is through a center piece 3 in split two equal parts.
  • a mold 4 is attached, the long sides of which are formed from a base 5, two parallel and perpendicularly opposing long side walls 6, 7 and the opening on the top and which is closed at the end by likewise parallel and perpendicularly opposing end walls 8, 9.
  • the bottom 5 is arched up to the central longitudinal line, as can be seen even better from FIGS. 2 and 3.
  • a hot melt adhesive application head 10 is arranged in a stationary manner above the mold 4. It is shown here as a rectangular box because it is designed in the usual way. This can be, for example, a product of the H 200 type from Nordson Corp., Atlanta / USA. Below the hot-melt adhesive application head 10 there is a hot-melt adhesive nozzle 11, with the aid of which the previously processed in a heating device, not shown here, i.e. heated and thus at least in the pasty state hot melt adhesive can be filled into the mold 4.
  • the middle piece 3 can be pushed back and forth in the directions of the double arrow A, this being possible, for example, by means of a corresponding rail guide and driven by a hydraulic or pneumatic cylinder, not shown here.
  • the center piece 3 In the end position, ie after the hot melt adhesive has been filled in, the center piece 3 is again in the position shown here.
  • the cross-sectional view according to FIG. 2 shows the device 1 after a hot-melt adhesive bead 12 has been filled into the mold 4.
  • the hot-melt adhesive bead 12 has such a low temperature and is therefore so viscous that it does not flow, ie does not fill the mold 4.
  • the right side of the plate 2 in this view has a stop web 13, 14 in the longitudinal and transverse directions, to which a cover sheet can be aligned in relation to the form 4. This can be seen from the cross-sectional illustration according to FIG. 3.
  • a cover sheet 15 is placed over the form 4 so that it abuts the stop bar 13 with a longitudinal edge and the stop bar 14 with a transverse edge.
  • a press ram 16 which can be moved in the directions of the double arrow B presses the part of the cover sheet 15 located above the mold 4 slightly into this mold, as a result of which the bead of hot-melt adhesive 12 is evenly distributed within the mold 4 until it completely fills the cavity thus formed fills out.
  • the side walls 6, 7 folds 17, 18 emboss into the cover sheet 15, through which the latter is divided into a cover spine 19 and cover covers 20, 21 adjoining it on both sides.
  • the press ram 16 can be driven, for example, in a manner known per se via a hydraulic or pneumatic cylinder which is omitted here for the sake of clarity.
  • the press die 16 itself is constructed in two parts. It has a rigid press plate 22, on the underside of which a worktop 23 made of elastic material is fastened. The elasticity of this worktop 23 is such that the side walls 6, 7, 8, 9 penetrate it so deep that a good seal of the mold 4 is achieved and the binding spine 19 is pressed so deep into the mold 4 that the cavity is completely filled with hot melt adhesive 12.
  • the cover sheet 15 can be lifted up from the base 2 and thereby takes the hot melt adhesive 12 out of the mold 4. It then has the finished shape shown in FIG. 4. Due to the high arching of the bottom 5 of the form 4, the hot melt adhesive 12 has a trough-shaped depression 24 in cross section, which favors the holding together of the paper sheets placed on it when it is bonded and also ensures that the outer paper sheets are bound in a particularly thick hot melt adhesive layer.
  • the embossed folds 17, 18 can be seen, which separate the cover spine 19 from the cover covers 20, 21.
