APPARATUS FOR MAKING SWATCH CARDS FIELD OF THE INVENTION The present invention relates to an apparatus for assembling swatch sample cards. More particularly this invention concerns an apparatus for bonding textile swatches to cards for display of the textiles.

BACKGROUND OF THE INVENTION A textile sample card has a plurality of swatches which are adhesively bonded to a paper card. Identifying indicia is printed on the card so that the prospective customer can see just how the textiles look and feel and then make his order according to the given information. A textile manufacturer generally produces new lines of fabrics several times a year, so that he must periodically send out new swatch sample cards to his customers.

Such cards can be made by hand by painstakingly gluing the swatches to a card. This method is quite expensive so that recourse is normally had to automatic machinery which is loaded with stacks of swatches and with the printed cards and then glues the swatches to the cards in the desired positions. Such machinery is quite expensive, however, so that a small textile mill is forced to choose between the expensive alternatives of either buying such a machine and letting it stand idle most of the time or having the swatch cards prepared by a jobber.

OBJECTS OF THE INVENTION It is therefore an object of the present invention to provide an improved apparatus for assembling swatch cards.

Another object is the provision of such an apparatus which is relatively simple and therefore inexpensive to buy and use.

A further object is to provide a swatch-card making machine which can be used to produce all types of cards from different sized swatches and support cards.

Yet another object is to provide a machine which can employ gum-arabic types of adhesives particularly adapted for use on thin textiles.

SUMMARY OF THE INVENTION These objects are attained according to the present invention in an apparatus wherein a table has a gluing station and an attachment station. Adhesive is applied to the cards according to a predetermined pattern at the gluing station and the swatches are then applied to the glued areas in the attachment station. A platen is displaceable in horizontal guides above the stations into a rearward position giving access to the stations and a forward position above and covering these stations. Means is provided to vertically reciprocate this platen in its forward position so as to simultaneously press a card down in the gluing station and to press a glued card down in the attachment station in a single operation.

Such an apparatus is quite versatile since the arrangement of the stacks of swatches in the attachment station on the table can be easily changed. Similarly the glue-applying means in the gluing station can be changed so as to apply the glue to the cards in virtually any desired arrangement. The operator of the machine takes the glued card out of the gluing station and sets it against a set of stops in the attachment station, and

places a new clean card in a predetermined position in the gluing station. The cards. according to another feature of this invention. can be removed from the attachment station automatically and dropped in a stack.

The gluing means at the gluing station may be an adhesive-filled tray provided with a plurality of felt or sponge blocks arranged in a predetermined array and projecting above the rim of the tray. The unglucd card is held on a vertically displaceable rack above the tray so that when the platen presses it down it receives gluc at predetermined locations as it is pressed against the blocks. Alternatively the card is held in the gluing station and a screen-printing type of glue applicator, which is carried on the platen. presses against it and applies glue to it in predetermined locations. depending on the screen.

The attachment station according to this invention supports a plurality of stacks of swatches. This station has a pegboard type of bed on which stops or guides are releasably attached for exactly positioning the stacks of swatches according to the desired position. Springloaded pins engageable through the bed with the undersides of the stacks insure that each stack is pressed firmly against the glued card when the platen presses this card down against the stacks. The bed spring loaded and vertically displaceable so that as the glued card is pressed down on the tops of the stacks it presses these stacks and their bed down against the springloaded pins to press and glue the top swatch of each stack to the appropriate area of the glued card.

DESCRIPTION OF THE DRAWING The above and other objects. features. and advantages of the invention will become more readily apparent from the following description, reference being made to the accompanying drawing in which:

FIG. I is a perspective view of the apparatus according to the present invention;

FIGS. 2 and 3 are front sectional and top views. respectively, of the gluing station of the apparatus of FIG. 1;

FIGS. 4 and 5 are views similar to those of FIGS. 2 and 3, respectively, of the attachment station of the apparatus of FIG. 1;

FIG. 6 is a vertical section through another embodiment of the apparatus of this invention; and

FIGS. 7 and 8 are schematic diagrams illustrating the functioning of the machines of FIGS. 1 and 6, respectively.

SPECIFIC DESCRIPTION The apparatus according to this invention has a housing 1 whose top is formed as a table 40 on which are provided a gluing station 4 and an attachment station 5. A large rectangular traverse or platen 2 is shiftable on wheels 20 inside guide channels 3 carried on blocks 30 which are vertically reciprocal on guide rods 6 by means of a piston rod 7 of a pneumatic ram (not shown). The platen 2 can be displaced manually by means of handles 2 associated with buttons 2" both of which must be pressed to actuate the piston rod 7 to drop the platen 2 down onto the table 1. Other controls 11 are provided on the housing 1 which operate a cylinder 31 which reciprocates the platen 2 horizontally in the guides 3 between the back position illustrated in FIG. 1 and a forward position above the

stations

4 and 5. Again dual controls are provided to prevent the operator's hands from getting caught in the machine.

As shown in FIGS. 2 and 3 the table 40 is provided at the glueing station 4 with a tray 4] partially filled with glue L. A plurality of felt blocks 42 are fixed to the tray in a pattern determined by the type of swatch card to be made. A rack or grid 43 having thin cross members 47 is supported above the tray 41 on four rods 44 slidable in sleeves 45 underneath the table 40. Springs 46 in these sleeves 45 urge the rods upwardly into the illustrated positions. The blocks 42 project up beyond the tray 41 by a distance greater than the vertical thickness of the cross members 47 so that when this rack 43 is dropped down on top of the tray 41 the blocks 42 project through it.

The attachment station shown in FIGS. 4 and com prises a pegboard type of perforated support 5] formed with a regular array of throughgoing holes 49 which register with a similar array of holes 56 in the table 40 underneath it. This support has sides 50 supported on rods 58 slidable in sleeves 59 like the rods 44 of the grid 43. A stack of swatches M is held between four stops or blocks 52 formed with pins 53 which fit snugly in the holes 49 so that this stack of swatches M may be positioned virtually anywhere on the board 51. Rods 54 slidable in tubes 55 having collars 48 overlying the table 40 are spring-loaded like the rods 44 so as to project up from whatever hole the tube 55 is fitted to. A piece 57 of cardboard or the like underneath the stack of swatches M is engaged by the pins 54 when the support Si is pressed down by the platen 2 to force this stack up against the underside of a card. The platen 2 is hollow and is formed above the station 5 with a plurality of holes 12 so that when a pump 13 is connected to it a finished card can be picked up.

This device is operated as follows, as shown in FIG. 7:

A printed card K from a stack of such cards is positioned face down against stops 39 on the cross members 47 of the rack 43. This insures an accurate positioning of the card K Then the platen 2 is placed into the forward position above the

stations

4 and 5 and this platen is dropped. As it descends it first engages the back of the card K, and then presses the rack 43 down until the front of the card presses against the blocks 42 and takes up glue as shown at L.

The platen 2 is then lifted and displaced either manually or mechanically into the back position illustrated in FIG. I and the operator positions the glued card K still face down atop the several stacks of swatches M in a position determined by stops similar to the stops 39 or by markings. A new card K, is also set in the station 4 at this time.

The mechanism is then actuated to advance the platen 2, or this platen 2 is simply pulled forward, and again it is dropped to first engage the sheet, then press the entire support 5] down. The stacks of swatches M are pushed into firm contact with the glued regions of the card K, as shown at M. The platen 2 is then lifted and pushed back and the finished card MK is deposited face up on a pile by the operator, or the pump 13 can remove it from the station 5 automatically. The card K is then moved forward from the station 4 and a new card K is placed in this station 4.

FIG. 6 shows the left half of a platen 2' which is provided with a screen-printing arrangement useful for applying a gum-arabic or thick synthetic-resin type of glue L to the card K. in this embodiment the table 60 is hollow and formed with a multiplicity of tiny holes 61 so that constant evacuation of the interior of the table 60 holds the card K firmly in place.

A screen 62 spanned under a frame 63 constitutes the bottom of the platen 2' in the region of the station 4. A doctor-blade unit 64 has a body 641 slidable back and forth on the platen 2' on rods 642. A pair of

rubber doctor blades

644 and 645 are carried on a support 646 pivoted on the on the slide 641 at 643. A chain 67 driven by a motor 65 and spanned over a sprocket wheel 66 carried by this motor 65 and over an idler sprocket 68 adjustable at 649 for chain tension is connected to the pivotal support 646 at 647. A pair of adjustable stops 648 allow the support 646 to pivot through an angle a bisected by the vertical so that when the motor 65 is operated in one direction to pull the entire unit 64 toward itself the blade 645 serves to squeegee the glue L' through the screen 62 in those regions where it is permeable. Opposite operation of the motor, to advance the unit in the direction of arrow v tips the support 646 through angle a to pick up the mass of glue L' with the squeegee 644. The illustrated position is that one assumed at the end of a glue application cycle. Direction v is also the direction of displacement of the entire traverse 2' into the forward position.

This arrangement functions differently from the arrangement described with reference to FIG. 7. As shown in FIG. 8 a card K is placed front face up in the station 4 and glue L is applied to its top face. The glued card K, is then inverted and the swatches M are applied to it in the same manner as in FIG. 7. Thereafter the swatch-carrying card K is inverted and placed in the stack of finished cards MK.

The present invention allows a swatch card carrying swatches in virtually any pattern to be made in house by a textile manufacturer in a relatively inexpensive and easy-to-operate machine. A conventional solventtype glue L may be employed or a gum-arabic or synthetic-resin type of glue L for thinner swatches or for fabrics which do not readily take glue, such as synthetic-resin knits. The machine can be set up in a brief time by any average worker, and thereafter approximately three hundred swatch cards can be produced per hour.
