ALBERT BORCHARDT, OF HOBOKEN, NEW JERSEY.

CLOTH-PLAITING MACHINE.

SPBCIFTCATION forming part of Letters Patent No. 361,125, dated April 12, 1887.

Application filed December 1, 1886. Serial No. 220,338. (No model.)

To all whom/it may concern.-

Be it known that I, ALBERT BOROHARDT, of Hoboken, New Jersey, have invented certain Improvements in Oloth-Plaiting Machines, of which the following is a specification.

In cloth-plaiting machines as heretofore constructed the fabric is passed between intermittently-rotating creasing-rollers, one or both of which are heated. When these rollers are brought to rest, a reciprocating tuckingblade, the edge of which presses gently downward toward the surface of the lower roller and is armed with slightly-projecting teeth, catches the fabric lying upon the surface of the lower roller and presses it forward toward the line of bearing of the rollers upon the fabric, thus forming in the fabric a double bight or return-bend, which, when the creasing-rollers are again rotated, is pressed down and creased.

For the purpose of fastening the plaits in their folded position, cords which have been previously carried through a bath of mucilage or glue are fed between the creasing-rollers near the edges of the fabric, and are pressed down and made to adhere to the folds. This mode of fastening the plaits, however, results in the smearing of the rolls with gum or mucilage pressed out of the cord, and hence in the smearing, to a greater or less extent, of the fabric. This difficulty of course does not ensue when the gummed cord is not employed, in which case, .after the fabric has passed through the plaiting-machine, it is refolded and stitched along its longitudinal edges, for the purpose of retaining the plaits in their folded positions.

The object of the present improvement is to avoid the gumming of the creasing-rollers and the smearing of the fabric with gum, while automatically effecting the fastening of the plaits in the machine in which the plaiting operation is performed.

To this end the invention consists, first, in suitable mechanism for feeding between the edges of the plaited fabric and the upper creasing-roller strips of paper coated upon their under sides with an adhesive substance,

I which strips are by the rotation of the rollers pressed down along the edges of the plaited fabric.

The second feature of the invention consists in the arrangement, in connection with the lower creasing roller, of a tensionroller mounted in bearings which are preferably adjustable toward and from the lower creasingroller. The tension-roller, which may also be a heated roller, is circumferentially grooved, so. that it bears only upon the paper strips applied to the edges of the plaited fabric. The tension-roller is driven a little faster than the creasing-rollers, and thus exerts a slight pull, which stretches the plaited-fabric to which the paper strips have been applied with more or less tension over so much of the lower creasing-roller as intervenes between the line of bearing of the tension-roller and the line of bearing of the upper creasing-roller.

The prolonged contact ofthe plaited fabric and the strips adhering thereto with the surfaces of the heated rollers effects two useful results. It dries the paste or other adhesive material with which the under surfaces of the plaiting machine containing the improvements 7 are as follows:

Figure 1 is a front elevation of the machine, showing a portion of the lower creasing-roller in central vertical longitudinal section, for the purpose of illustrating a mode in which the rollers may be conveniently heated. Fig. 2 is a transverse section through the line as w on Fig. 1. Fig. 3 is an elevation of the righthand side of the machine. Fig. 4 is an elevation of the left-hand side of the machine. Fig. 5 is a horizontal section through the offset dotted line y 3 on Fig. 4..

F, and in the opposite direction by the retracting spiral spring E The driving-shaft F is provided with the crank G, for giving motion, by means of the pitman G,to the radius-bar Gflloosely mounted upon the shaft B of the upper creasing-roller, and provided with the pawl G for engaging the teeth of the ratchet-wheel B affixed to the shaft B, and thus imparting a prescribed range of rotating movement to the upper creasing-roller, and to the rollers geared thereto, during each revolution of the drivingshaft F. The upper creasing-roller is mounted in the usual vertical adjustable boxes, B.

One of the new features of the machine is the tension-roller h, to the hollow shaft h of which is affixed the pinion k which engages with and is driven by the spur-wheel G, affixed to the shaft 0 of the lower creasing-roller, O. The spur-wheel G is made slightly larger than the pinion h in order to drive the roller h a little faster than the creasing-roller O.

- The heating ofthe tension-roller may be effected, in the usual way, by means of the j ets of flame from a gas-pipe, h inserted through the hollow shaft h and affixed to the gas servicepipe h.

Another feature of the present invention consists of the paper-stri p reels 1' 1, upon which the paper strips i i, &c., are coiled, and from which the strips 12 t are delivered with such tension as may be due to the bearing upon the surface of the coil, in each case, of a brake, affixed to the end of a pivoted arm, i provided with an adjustable weight, '5 From the reels i z, respectively, each of the paper strips 2" is led by means of suitable guide-rollers downward to a paste-reservoir, j, and over a paste-roller, j, having its lower portion immersed in the paste or other fluid adhesive material, 3, contained in the paste-reservoir.

After passing over the paste-roller the strips 17-13 are respectively led under the upper creasing-roller, and are so guided that they are pressed downward by the upper creasingroller alongthe edges of the plaited fabric L as the latter passes through between the creasing-rollers. If the reels, guide-rollers, and pasting-rollers are properly adjusted, the strips of paper will be appropriately delivered between the creasing-rollers; but, as ameasure of abundant caution, each of the strips is carried between the adjustable guides k, which are secured by set-screws to the horizontal bar is, supported in the frame of the machine in a posiseen that the paper fastening-strips i are applied to the edges of the fabric concurrently with the creasing operation, and that the plaited fabric with the strips applied is therefore held in contact with the surfaces of the heated rollers for a sufficient length of time to dry the paste, and to thus permanently secure the plaits in their folded position, so that the plaited fabric can be handled without causing the unfolding of the plaits.

As the fastening-strips are applied to the edges of the plaited fabric, it is not necessary to remove the strips until after the fabric has been sewed to the object in connection with which it is to be used, after which the paper fastening-strips, if they show, can easily be torn off.
