FABRIC-PRINTING MACHINE.

Application med Iarch 15, 1927,

This invention relates to fabric printing machines and has for its object to provide improved means for the production of the desired patterns upon the fabric. VA further object of the invention is to provide simple and effective means for producing duplex or double sided pattern eii'ects upon the fabric and to neutralize the effect of any colour or moisture which may pass through 1o the fabric on to the printing roller and be offset on to theA fabric. A still further object is to provide readily operated means for enabling the machines to overprint in accurate register with a previously printed designl or pattern.

The invention comprises the improved printing arrangements hereinafter described and claimed.

Referring to the accompanying sheets of explanatory drawings z- Figure 1 is a side elevation giving a view of a. complete machine having the invention applied thereto.

Figure 2 is an end elevation showing to a larger scale and in diagrammatic form, the arrangement of the driving gear and the printing and other rolls.

Figure 3 is a side elevation and Figure 4 a sectional end elevation further showing the said gear and to a largerl scale than that of Figure 2.

The same reference letters in the different views indicate the same or similar parts.

The fabric to be printed passes between the nip of the printing roller a and one colour roller b (Figures 1 and 3) whilst the other colour roller 'c rotates in contact with the printing roller a preferably at a point diametrically opposite to the nip of such 40 roller a. and the first mentioned colour roller b. It will be seen therefore that whilst one side of the fabric d is'printed on directly by the printing roller the other side receives its pattern dueto the pressure of the raised portion of the printing roller upon the colour roller b at the opposite side of the fabric.

The colour roller c which furnishes colour directly to the pattern on the printing roller a, serves also to clean the said pattern of any colour whose properities may have been weakened by passage through the fabric (which may or may not have been chemically treated) from the other colour roller b.

-. The two colour rollers b and o are rotated in unison through a chain e or like positive p and worm g).

drive. The driving power is received from any suitable source through a gear wheel as f (Figure 2) or otherwise. The printing roller a is driven from one colour rollerI as b by means which permit of an angular adjustment of the printing roller with relation to the colour rollers whilst the machine is running so that the pattern printed by the said roller can be maintained 1n fit with any pattern which may have been previously printed upon the fabric.

In the example illustrated by the drawings, the said driving means of the printing roller a comprise a. wheel g secured to the shaft of said roller and geared through the idle wheel h to the wheel Z which is formed integrally with the internally toothed wheel y'. The said combined wheels i and y' are free upon the shaft lc of the colour roller b, the internally toothed wheel j (Figures 3 and 4) gearing with planet pinions as Z which mesh with a sun pinion m secured on the shaft 7c. The planet pinions Z are carried freely upon short spindles as 'n secured to a worm wheel o (mounted freely on the shaft c which can be rptated by ahand wheel Normally when the hand worm 'wheel o are stationary, the printing roller a is driven from the sun wheel m on the shaft Za of the colour roller b, the planet pinions Z running idly on their fixed spindles n for the transmission of the motion from the sun wheel or pinion m to the internally toothed wheel y' from whence it is transmitted through the wheels i, he, g to the printing roller a. The said gear wheels i, h, g are so proportioned that the printing roller a1 and the colour rollers I) and o all have the same peripheral or surface speed. If, however, the hand wheel p is turned in one or other direction, the printing roller a is slightly speeded up or slowed down or has a small angular movement imparted thereto, relatively to the colour rollers b, c as may be required ,to adjust its pattern with relation to the pattern previously printed on the fabric. Thus the machine attendant can lwatch the register or fit of the pattern being printed and adjust the printing roller to correct any lack of fit due to cloth stretch or otherwise.

The colour is supplied to the rollers b and c by bands as r, each band passing round one of such rollers and also aroller as s, which rotates, by surface contact, theusual distributing roller as t in the colour box u.

The machine as illustrated at Figure 1 'is driven by means of a belt lv. The Wheel w gears with the wheel f on the shaft c.

What I claim is 1. In fabric printing machines, the combination with a printing roller having a raised pattern thereon, of two colour rollers, each supplied with colour by an endless band or sleeve which passes round the colour 0 roller and a` further roller rotating in contact with the colour box roller.

2. In fabric rinting machines having the combination clgimed in claim 1, the provision of means for driving the colour rollers in unision, of means for driving the printing roller from one of said colour rollers and for the angular adjustment of said printing roller relatively to the colour rollers for the purpose aforesaid.

In testimony whereof I have signed my 20 name to this specification.

ARTHUR CROMPTON.
