Trenton, N. Automotive Fibres,

Inc.,

poration of Delaware Application my 20, 1942, Serial No. 451,628 19 Claims. (01. 918) This invention relates generally to the manufacture of carpets, rugs and the like and refers more particularly to the manufacture of cemented pile carpets wherein the pile surface of the carpet is composed of a multiplicity of individual upstanding fibers that simulate ordinary woven pile in appearance.

Preferably the carpet ismade by depositing the individual fibers onto a cement or adhesive covered base while the latter is being vibrated, however ln the present instance the invention is characterized by (l) successive deposits of different types or grades of fibers onto the adhesively covered base, (2) the uniform feeding and uniform deposition of the fibers, (3) the removal from the base of loose or excess fibers before successive deposits are made, (4) the uniformity in weight and length of the fibers initially deposited, (5) a more perfect initial formation of the fibers, (6) the use of a longer pile material than ordinarily employed, (7 the positive breaking up and carding of the flock into individual fibers, (8) the controlled supply of fibers from the feed units, and (9) the improved or more equalized vibrating means for the base to obtain a more uniform and deeper penetration of the fibers into the adhesive or cement covering on the base.

Thus, one of the essential objects of the invention is to obtain a better carpet, i. e., a carpet having a better pile surface.

Another object is to provide an improved means for making such a carpet.

Other objects, advantages and novel details of construction of this invention will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings, wherein:

Figure 6 is an enlarged elevationalview of the first feed unit, with parts broken away and in section;

Figure 8 is a side elevation of the first feed unit as illustrated in Figure 1 but showing a mod fied agitator assembly in combination therewith;

Figure 9 is a vertical sectional view through the material X before being flocked;

Figure 10 is a vertical sectional view through a carpet made in accordance with my invention. Referring now to the drawings, A and B, respectively, are feed rolls of calendered material to be flocked, C is a vertical series of tension rclls for said material, D is an adhesive doctor knife or cement spreader knife, E, F and G, respectively, are vibrator or heater assemblies for the material, H is a roll for pulling material from the feed olis A and B over the vibrator assemblies E, F and G, respectively, J, K and L, respectively, are flock feed units, and M, N and 0, respectively, cleaning oil or removing loose or excess fibers from the adhesive or cement upon said material.

As shown, the rolls A and B cally apart and are carried by a suitable frame It at one end of the machine. Preferably the material on the lower roll A is used first and then the material on the upper roll B is used. If desired, the lead end of the material on the upper roll B may be spliced or otherwise secured to the tail end of the material on the lower roll A to provide a continuous operation. In each instance, the material X may be burlap I, woven cloth or a synthetic sheet or paper having the proper tensile strength, or a smooth sheet of any other suitable material calendered to uncured sponge rubber 8, or some other suitable substance having resilient qualities. Such material is drawn from the rolls A and B around the tension rolls C and over the vibrator or beater assemblies E, F and G, respectively, by the puller r'oll H at the other end of the machine.

The tension rolls C may be any suitable conare spaced vertithe machine. Suitable means (not shown) may be employed for driving the tension rolls C at approximately five (5) per cent slower speed than the puller roll H.

After leaving the tension rolls 0 the material having the rubber side thereof lowermost passes over idler rolls H and I2, respectively, onto the first agitator or beater assembly E. However, before it reaches the assembly E, the upper surface of the material is covered substantially with a layer 9 of suitable adhesive substance or cement somewhat inferior grade of flock is preferably .used in this feed unit. Such flock is selected as a secondary fillfor the initial formation on the adhesive or cement covered material X to ,help build up a solid pile on said material.

The third flock feed unit L is also spaced above the second agitator assembly F and preferably comprises a vertical chute provided at its lower discharging end with suitable carding rolls 60 and GI, respectively. The same grade of flock used in the second feed unit K or a more inferior grade of flock may be used in the third unit to make the final fill for the pile previously formed on the material X.

The suction nozzles M, N and 0, respectively, arepreferably located at spaced points of the machine to clean off or remove loose or excess fibers from the adhesive or cement covered material X after the fibers have been deposited thereon from the feed units J, K and L, respectively. As shown, the first nozzle M is between the first and second feed units J and K for cleaning up the material X after the initial deposit is made thereon and before the deposit from the second feed unit K is made; the second nozzle N is between the second and third feed units K and L for cleaning up the material X after the second deposit and before the deposit from the third feed unit is made; and the third suction nozzle is at the rear of the third feed unit L for making a final clean up. Such nozzles M, N and 0 may be connected by suitable ducts to the storage bins from which the flock for the respective feed units is obtained. Preferably the first nozzle M is cOnnected to a duct 62 that leads to the storage bin 35 for the first feed unit J and contains a suitable suction fan or blower 63 for drawing ofi the material X and returning to the first bin 35 any loose fibers that did not become imbedded in the cement or adhesive substance on said material after being discharged from the first feed unit J. In this connection, the duct 62 has a branch 64 that extends from the bottom of a trough 65 located below the first agitator assembly E for receiving any fibers overflowing the sides of the endless conveyor l3. Thus, the fibers that are discharged from the first feed unit J and fail to be imbedded in the cement or adhesive substance on the material X are returned to the storage bin 35 for the first feed unit J to be used again.

Likewise, the second suction nozzle N is connected to a duct 66 that leads toa second storage bin (not shown) for the second feed unit K and contains a suction fan or blower 67 for drawing ofi the material X and returning to the second bin mentioned any loose fibers that did not become imbedded in the cement or adhesive substance on the material X after being discharged from the second feed unit K.

The third suction nozzle 0 is connected to a duct 68 that leads to the third feed unit L and that contains a suction fan or blower 69 for drawing off the material X and returning to the third feed unit L any loose fibers that did not become imbedded in the cement or adhesive substance on the material X after being discharged from the third feed unit L. However, in this instance, there is a branch duct that leads from the duct 68 to the second bin mentioned, and there is also a supply duct 1| that leads from the second bin mentioned to the duct 68 on the intake side of the blower 69. A suitable directional damper 72 may be provided at the juncture of the ducts 68 and 10 to control the flow therethrough of fibers from the blower 69.

fore the flock is deposited thereon.

Thus, with this arrangement, it w'illbe apparent that provision has been made in the first instance fordepositing one type of flock onto the material X, then cleaning the material X, then depositing another type of flock onto said material, then again cleaning the material X, finally depositing the same type of flock again onto the material X, and finally again cleaning the material X before completing the process. Hence, the surface of the adhesive substance or cement on the material X is clean in each instance be- Actually, each successive deposit of fibers may be accomplished withoutinterference on the material X with loose fibers that would form obstacles that would prevent the deposited fibers from becoming imbedded in the adhesive substance or cement on such material. As a result more of the fibers deposited will become imbedded in the adhesive substance or cement to provide a denser pile formation. Moreover, it'will be apparent that the three agitator assemblies E, F and G, respectively, are. located at such points relative to the feed units J, K and L, respectively, that the fibers imbedded in the adhesive substance or cement on the material X will sink farther. and farther into such adhesive substance or cement as the material advances over and is agitated by the respective assemblies E, F and G. In fact, by the time the fibers pass over the third and final agitator assembly G they will sink to a point near the bottom of the cement or adhesive substance on the material X, hence such fibers will not only be dense as aforesaid but will also be anchored firmly and solidly as desired. As a result, a solid, well-anchored pile is provided on the material X.

If desired, some other means such as the cooperating rolls 8E! and BI, respectively, may be employed instead of the electric vibrators 32 and 33 after the pile has been formed as aforesaid on the material X to push the fibers of the pile down farther into the cement or adhesive substance on said material for better anchorage purposes. As shown, the lower roll 8| is an idler roll and engages the underside of the material X, while the upper roll 80 is a pressure roll and has suitable adjusting means 82. Preferably the periphery of at least the upper roll 80 is covered with sponge rubber 83 or the like for engagement with the pile formed on the material X.

After the pile mentioned is formed, the material X provided with such pile is advanced through an oven or other heating chamber (not shown) where the sponge rubber 8 on the underside of the material X is cured and where the adhesive substance or cement 9 in which the pile is anchored is dried or cured to provide the finished product.

In Figure 8 I have illustrated a slight modification wherein electro-static equipment R is provided instead of the agitator assembly E beneath the first feed unit J. As'shown, an electrically charged reciprocating screen of conventional design is supported between the fancy roll 45 and the endless conveyor l3 in position to receive the fibers discharged from the unit J, while an electrically charged electrode BI is located immediately below the top flight portion of the endless conveyor as an agitator for the material X. Thus. the electrically charged screen 90 causes the fibers to dance up and down and fall in a straightened condition into the adhesive substance or cement 9 on the material X, while the charged electrode 9| Will vibrate the material X so that such fibers will be imbedded endwise in the cement or ad substance mentioned. Otherwise the construction and operation of the parts illustrated in l'lgureiiarethesameasinllgurel.

In use, the material x from the feed rolls A and B will be covered by the doctor blade D with a suitable layer 9 of adhesive substance'or cement which will receive successively three deposits of fibers from the feed units J, K and L, respectively, as the material is advanced over and vibrated successively. by the three agitator assemblies E, 1'' and G, respectively. The initial deposit from the feed unit J consists of selected, well-balanced fibers of substantially uniform length and weight to provide a better and more uniform initial formation on the material X, while the second and third deposits may be of an inferior grade of fibers. The suction nozzles M, N and 0, respectively, will effectively remove loose fibers from the adhesive substance or cement 9 on said material to insure a clean surface for each successive deposit of fibers. Hence, a denser formation of the fibers on the material X may be obtained. The arrangement of the agitators E, F and G for the material X insures the proper anchorage of the fibers in the adhesive substance or cement 9 because successive vibrations cause such fibers to sink farther and farther into such adhesive substance or cement. Thus, the pile formed by the fibers on the material X will be denser and anchored better than heretofore.
