    I claim:1. In combination with a data processing machine including a form-aligner device and having a web of paper moving therethrough at a high speed, paper holding means adapted to be secured to the form-aligner device of the machine and comprising a pair of substantially identical oppositely disposed holder members, each of said holder members comprising a relatively short leg and a rela50 tively long leg disposed at substantial right angles with respect to each other, each of said short legs provided with apertures for facilitating securing of the holder members to the form-aligner whereby the holder members are disposed slightly inwardly therefrom, detent means pro55 vided on each short leg for cooperation with the formaligner to stabilize the holder members against vibration of the machine during operation thereof, said short legs being slightly bent along the longitudinal center line thereof to preclude hindrance of the operating portions of the machine, each of said long legs being bent with respect to the associated short leg whereby the long leg extends upwardly from the machine a short distance and being further bent whereby the greater portion thereof extends rearwardly of said short legs a sufficient distance 65 for precluding back-folding of the paper being processed in the machine due to passage of the paper over the rear portions of the machine.

    In combination with a data processing machine inγθ eluding a form-aligner device and having a web of paper moving therethrough at a high speed, paper holding means adapted to be secured to the form-aligner device of the machine and comprising substantially identical but oppositely arranged holder members, each of said holder 75 members comprising a relatively short leg and a relatively with a pair of oppositely disposed plate members 30 and 32 of substantially identical configuration. The plate members 30 and 32 are spaced slightly forwardly of the web 16 and extend over a portion of the opposite side edges 26 and 28 thereof, respectively, and as clearly 5 shown in FIG. 1. Each plate member 39 and 32 is normally provided with a longitudinal slot 34 disposed in alignment with the apertures 24 of the corresponding side edge of the sheet 16. It will be apparent that the slots 34 provide clearance for the teeth of the wheel (not 10 shown) which engage the apertures 24, as hereinbefore set forth. The plate members 30 and 32 function to hold the paper or sheet 16 in a position substantially adjacent the form-aligner device 22 for assuring that the teeth will engage the apertures 24, and to preclude the 15 web 16 from falling forward as it leaves the platen 20, as is well known. However, the portion of the web 16 extending rearwardly from the opposed plates 38 and 32 may fold back on itself during the normal operation of the machine 10 whereby over-printing thereon may occur. 20 The plates 30 and 32 are each usually further provided with a pair of spaced slots 36 and 38 and an aperture 40 in the proximity of the upper edge thereof. In order to preclude accidental back-folding of the sheet 16, a pair of paper holding devices 42 and 44 are secured to 25 the plates 30 and 32, respectively, in a manner as will be hereinafter set forth. The devices 42 and 44 are substantially identical, as clearly shown in FIGS. 2 and 3. The holder 42 is preferably considered the right hand device, whereas the 30 holder 44 is considered as the left hand device. The description of the device 42 will be set forth in detail, it being understood that the holder 44 is of a similar construction, but opposite or reversed therefrom. The holder 42 is of a substantially L-shaped configuration wherein 35 the longer leg 45 thereof extends rearwardly from the plate 30. The shorter leg 46 of the holder 42 extends at a right angle from the leg 45 and is provided with an aperture 48 adapted to be aligned with the aperture 40 of the plate 30 whereby a screw (not shown), or the 4θ like, may be utilized for securing the holder 42 to the front face of the plate 39. The lower edge of the leg 46 is further provided with a pair of spaced detents 50 and 52 for engaging the spaced slots 36 and 38 of the plate 30. The engagement between the slots 36 and 38 and detents 50 and 52 precludes wobbling or pivoting of the holder 42 about the connection at the aligned apertures 40 and 48, thus assuring a stability for the holder 42 during the normal vibrations inherent with the operation of the machine 10. It will be apparent that the detents 50 and 52 are depicted in an exaggerated size in FIGS. 2 and 3 for purposes of illustration. In addition, the leg 46 is preferably slightly bent substantially along the longitudinal center thereof as indicated at 54 to assure no interference between the device 42 and the plate 30 thus providing no hinderance of the normal operation of the machine 10. The slight transverse bending of the leg 46 in no manner interferes with the engagement of the detents with the respective slots. The longer leg 45 is bent at 55 with respect to the leg 46 and is curved slightly backward at 56, as viewed in the drawings, whereby the leg 45 extends upwardly a short distance from the leg 46 and then rearwardly therefrom at a slight angle. Thus the leg 45 extends rearwardly at an angle from the plate 30 whereby there is no interference with the normal travel of the web 16 through the machine 10. The legs 45 of each holder device 42 and 44 function as stop members to positively preclude any upward or forward movement of the web 16 travelling rearwardly from the form-aligner 22 or plates 30 and 32. It is to be noted that the leg 45 of each holder 42 and 44 extends rearwardly from the respective plates 30 and 32 a sufficient distance to assure that the web 16 leaving the platen 20 will travel through the machine 10 smoothly without back-folding in the
