8 Claims.

This invention, relates to means for stripping the work from the padded roll of a flatwork ironer, at the exit end of the pressing zone between the roll and its cooperative heated chest.

The principal object of the invention is thus to cause the work as it leaves the pressing zone to follow the chest and thus be led between the next succeeding roll and chest of the ironer, so as to prevent the work instead following the roll.

Another object of the invention is to provide that the padding of the roll, which is loosely wound thereon, shall maintain its wound position thereon.

Further objects are to accomplish these principal purposes in the most advantageous manner possible as will be apparent from the following description taken in connection with the accompanying drawing, in which Figs. 1 and 2 are conventionalize'd sectional views each showing an embodiment of the invention applied to a single unit of a flatwork ironer.

With reference now to the embodiment of Fig. 1, 1 is a chest and 2 its cooperative roll, it being understood that in operation the chest is maintained heated as by steam introduced within its hollow, and the roll is padded as at 3 and faced with a'sheet of fabric overlaid in roll form about the padding. It will also be appreciated that the roll 2 is mounted for rotation upon its axis while bearing against the polished'ironing face of the chest 1 and is provided with a suitable drive so that it operates against the chest in the direction of the arrow. The flatwork ironer usually includes a series of such units with the chest partsdisposed in abutting relation with each other so that their combined face presented toward the rolls offers no obstruction to work progressing thereover from roll to roll, each roll bearing upon its chest, and all of the rolls being driven in the same direction; so that work started between the first roll and its chest will be caused by the operation of the rolls to pass the chest, and thence outwardly over the chest 1 and from the roll to the right in Fig. 1. In such "spaced from the roll.

the leading band ends 5.

operation there is an occasional tendency of the WOIfk, when leaving the pressing zone, to follow the roll upwardly instead of following the chest face away from the roll as intended. Also, there is a tendency of the loose end of the roll facing, indicated at 4, to drop onto the chest ahead of the roll instead of remaining fiat upon the roll as intended. These are the malfunctions which this invention corrects.

According to the invention I provide a number of thin narrow stripper bands of sheet metal arranged in spaced relation with each other along the roll and chest, and each disposed in the direction of work travel, with intermediate parts between the roll and chest. Each band 7 has a leading part 5 secured in any convenient manner as to a bar 6 running along ahead of the roll, suitably mounted in any convenient manner upon the frame of the ironer, and. sufficiently. elevated above the chest 1 to permit feeding of the work between the band ends5 and the chest.

Each band extends at its following end '7 beyond the roll, overlying the chest, and is there provided with means for yieldably maintaining it In the arrangement of Fig. 1 such means are integral with the bands and comprise simply parts 8 thereof folded back upon themselves and curved so that their extremities will lie substantially fiat against the roll. Preferably, also, the parts 8 are so proportioned and arranged that the parts '7 will not only be spaced from the roll but will be yieldably maintained to bear upon the chest.

Operation will be apparent. The work is-introduced ahead of the roll between the chest and The work progresses through the pressing zone substantially unaffected by the bands which have very slight aggregate area against the work in that zone. As the work emerges from the pressing zone, the

' band ends 7 strip it from the roll so that the work cannot follow the latter and consequently instead advances over the face of the chest.

The bands are, of course, polished and thin enough so that they do not materially embed' themselves in or otherwise substantially affect the roll face. They may be of spring material but in any event they have sufilcient flexibility and resilience that if the parts 7 are urged by the parts 8 against the chest, the pressure is not sufficient to prevent the works progressing from the pressing zone between the chest and the parts '7. H e

It will be evident that the parts 8 provide a certain drag upon the roll sufficient to maintain the end part 4 of the roll facing from slipping ahead of the roll.

With reference now to the modification of Fig. 2, the arrangement is generally as before, with the exceptions to be noted. The stripper bands are disposed in the same relation with each other, extending between the roll 2a and the chest 1a, with their leading ends 5a secured to the member 6a.

The following ends 7a are interconnected. by a transverse member 10 secured to the stripper band ends as by welding thereto in overlying relation therewith as at ll, so as to present no obstruction tothework. The member 10 is arched between the stripper bands as indicated so that it. cannot be engaged by the leading edge of the work. A member 8a is secured to the transverse member 10 preferably underlying the latter and welded thereto, intermediate each pair of stripper bands, and arranged to bear uponthe roll Zainthe same manner and for the same purpose as the members f Fig. l'. 7 By thearrangement of Fig. 2 the stripper bands are positively spaced. along the roll and the following end lct of each has slightly more flexibility thanin thearrangement of Fig. 1. As in Fig. l, the parts may be arranged merely to maintain theends 7a of. the stripper bands away from the roll 2, but preferably the arrangement is such that these band ends 7a bear against the chest, yieldably to maintain the work thereagainst. 7

As. to. insertion and removal of the stripper bands, it will be appreciated that the roll may be raised somewhat from the chest for the purpose, by arrangements usually provided in flatwork ironers as forrepadding the rolls and preventing the scorching of their padding during periods of idleness.
