having a layer of loosely felted,nonwoven fibrous material adhesively secured to one surface thereof. This padded backing sheet, as is vcommon in practice today, is covered with a section of woven fabric finish material which is tightly stretched l5 overl thel padded surface of the backing sheet and secured in position thereon.
The particular inner trim panels with which the improved method of the present invention is primarily concerned, have-embossments or other decorations on the exposed surface thereof, which decorations are formed by cutting through the padding material and forming the surface of the padding to a predetermined desired surface configuration. After thev fabric finish material has 5 been applied to the padded backing sheet the fabric finish material is preformed to the configuration of the padding material and adhesively `bonded to the backing sheet in the zones in which the padding material has been cut, in order not o only to' maintain the padding material in predetermined position on the backing sheet, but at the same time to reproduce in the fabric cov.-
ered surface of the trim panel the ornamental decoration desired.`
It is a primary object of the present invention to provide an improved method of manufacturing inner trim panels, which method is exceptionally cheap to` practice, and which inherently resultsthe present invention to provide a method of forming inner trim panels which method results in a very substantial saving in thelmamountV of adhesive necessarily used without 'in any way impairing vthe trim panel construction produced.'
and enacting a consequent reduction in the cost .t of manufacture.
The present invention contemplates the pro-V vision of n'ovel and improved mechanism for applying adhesive material to predetermined portions of the padding and backing sheet at the time the padding of the backing sheet is cut and formed to the predetermined desired configuration. i Y
Still another object? of the presentfinvention. is to provide novel means for cutting the fibrous padding material, which cutting means at' the same time serves to provide additional adhesive.
material to the particular zones of the padding 'l0 material where said adhsive will be most useful. Many other and further objects, advantages and features of the present invention will become more clearly apparent from the following specication when considered in connection with the 15 accompanying drawing forming a part thereof.

Fig. is an enlarged fragmentary sectional view similar to Figs. 6 and 7 illustrating in detail the cross-sectional configuration construction of the improved inner trim panel.
With more particular reference to the drawing, it will be readily understood Ithat the specific steps hereinafter enumerated constitute merely one specific preferred form of the method disclosed in the present application, the scope of which is clearly dened in the appended claims.
In the manufacture of inner trim panels in accordance with the method herein disclosed, a backing sheet I5 is provided, which backing sheet is preferably formed from a suitable section of a relatively stiff, hard pressed cardboard or other relatively stii sheet material. This backing sheet I5 is cut or stamped out in order that its peripheral configuration will be substantially identical with'the pheripheral configuration of the inner trim. panel which it is desired to produce. In Fig. 1 ofthe drawing is shown a completed inner trim panel manufactured in accordance with the method ol the present invention, and it will be readily understood that the trim panel therein disclosed is primarily designed for covering the interior surface of a yvehicle door. Manifestly, the particular shape of the inner trim panels to be produced forms no part of the present invention, and the form shown in Fig. 1 is merely illustrative of one form which the improved inner trim panelmay take.
After the backing sheet I5 has been blanked or stamped out to the predetermined desired configuration, liquid adhesive i6 is deposited upon the surface of' the backing sheet. While, if it is desired, the liquid adhesive I6 may be sprayed or painted over the entire surface of the backing Y sheet, it has been found satisfactory and quite practical, merely to apply this adhesive as shown,
to predetermined areas of the backing sheet and specifically to such areas as will lie underneath the particular portion of the subsequently applied padding material which it is desired to form in upon the panel.
If the adhesive material I6 is only applied on certain localized zones of the backing sheet, it will be readily appreciated that a substantial sav-V ing in adhesive material may be made. After the application of the adhesive material I6 to the backing sheet I5, a layer of loosely felted, woven, fibrous material I'l is applied to the surface of the packing sheet. This loosely vfelted nonwoven, fibrous mat or pad may conveniently be generated from jute fibers and is preferably blanked or stamped out in order 4that its peripheral configuration will. be substantially congruant to the peripheral conguration of the cardboard backing sheetli. It will be readily appreciated that this layer of non-woven fibrous padding material may be applied to the exposed surface of the cardboard backing sheet while the adhesive material Il is damp and that the adhesive maferial Il will serve to retain this pad in-predetermined positionv upon the cardboard backing sheet. Y
-As'isclearly seenin Pig. 4 of the drawing, a press is provided which serves the purpose of forming the padding material to the lpredeter- V mined desired configuration and at the'same time finishY material to the cardboard backing sheet at variousY points throughout the surface thereof. While the press may take any suitable desired form, it preferably constitutes a bed which has in cooperation therewith a ram 2| to which a die 22 is secured by means of a frame 23 and screws' 24. This die 22 has mounted therein a plurality of cutting blades 25, which cutting blades are rigidly secured in the die member 22. These cutting blades 25 are preferably provided with a small recess in the crests or edges thereof in order to .provide two spaced relatively sharp cutting edges. The. recess between these cutting` edges serves, as will hereinafter be more clearly seen, to
attain adhesive material subsequently utilized in the formation of the improved inner trim panel.
The blades may be arranged in any suitable desired configuration throughout the die member 22 in order toproduce upon the padded backing sheet the particular design sought. In the specic embodiment of the invention disclosed in .the drawing, the inner trim panelV has the surface thereof decorated by three substantially parallel lines disposed inwardly from the marginal edges of the trim panelA and, consequently, the three knives 25 are utilized for thev purpose of producing these lines.
Before the knives 25 are utilized for the purpose of operating upon a padded backing sheet, an adhesive applying apparatus 28 is passed over the bed of the press. This adhesive applying apparatus includes in general a pan or dish 29 which is partially filled with suitable adhesive material such, for example, as Latex. A roller 30 is mounted 'upon arms 3l, which arms are pivoted in`the pan 30 and suitable spring means may be utilized for the purpose of urging the arms upwardly away from the pan 28 in order to urge the roller 30 carried thereby into engagement with the knives 25 carried by the die mem- Vber 22. .It will be readily appreciated that as the adhesive applying apparatus 28 is slid over the bed of the press, the roller 30 will engage the knife blades 25 and apply adhesive from the pan 23 thereto, the adhesive covering the crest portions of the knives and being carried in the groove between the cutting edges thereof.
After the adhesive material has been applied to the knife blades 25, the padded backing'sheet in the form substantially as illustratedin Fig. 3
is placed upon the bed of the press and the ram v padding material to the backing sheet without' substantially` injuring or' cutting the cardboard backing sheet. It will be readily appreciated that the adhesive material which has been -applied to the knife blades,'serves to bond together the ends of the fibers cut and retain these bonded ends closely together adjacent the cardboard backing sheet. As has been explained above, it is preferable to apply the adhesive material I6 only to certain localized zones of the backing sheet and in the specific embodiment of the invention illustrated and described herein, it will be understood that this liquid adhesive material Ii is only applied to suchr zones of the backing sheet as ,the knives 25 act upon. The cutting operation performedby the press shown in Figs. 4 and 5, is preferably performed while the adhesive material I6 is still wet in order that this adhesive will blend with the adhesive carried by the cutting knives.
After the completion of the forming operation by the press as shown in Figs. 4 and 5, the padded backing sheet will appearpsubstantiallyr as is illustrated in the enlarged fragmentary sectional `view in Fig. 6. It will be seen by reference to this figure that the cutting knives have served the purpose of applying additional liquid adhesive material to the bases of the channels or.. grooves formed in the padding material by the knives.
A section of fabric finish material 35 having a 4peripheral configuration substantially similar to but slightly larger than the padded backing sheet is stretched thereover and has themarginal edges 36 thereof adhesively secured to the reverse side of the backing sheet l5. After the marginal edges of this fabric finish material have been secured in position, the fabric covered padded backing sheet is preferably placed in a press of the type shown in Figs. 8 and 9. This press includes a bed Ill and a ram 4I. The ram 4I. serves tocarry a die 42 having a plurality of blades 43 therein. In the particular lform of the. invention illustrated herein where three substantially parallel lines are formed in the padded backing sheet, ithas been found preferable to mount the central of the three blades 43 by means of springs in order that thisblade willI normally protrude slightly further than the blades I3 on each side thereof. These blades 43 are arranged within the die 42 in substantially the same manner 4as the knives 25'were positioned in the die 22. As the ram of the press descends, the central of the blades I3 will enter the central channel which has been formed in the padding material and` urge the fabric finish material into this channel where the fabric finish material will be adhesively bonded directly to the baclng sheet. As the die descends further, as is clearly seen in Fig. 9, the springs serving to support the central blade I3 will be compressed and the blades 43 on each ofthe sides thereof will enter their respective channels and urge the fabric material therein, thus bonding this fabric finish material directly to the A cardboard backing sheet in the bases of these l channels. It will be readily understood that the utilization of the central spring pressed blade serves the purpose of tensioning the fabric finish material over the surface of the 4padded backing lsheet evenly and vuniformly and the`blades together serve to conform the fabric finish material to the configuration of the preformed padded backing sheet.
After the completion of "the operation performed by thepress shown in Figs. 8 and 9, the padded inner trim panel will appear in cross section substantially' as is illustrated in Fig. l0. It will be clearly seen that the fabric finish material is tensioned over preformed padding material and is bonded adhesively directly to the backing sheet in the bases of each of the grooves formed by the cuttingv knives 25.
The above described :method is merely illus'- trative of the generic inventive concept presented in this application. Many other and further modifications thereof falling within the scope' of the invention as defined inthe subjoined claims will become readily apparent to those skillei'in the art.
