referring now to the figures of the drawings in detail and first , particularly , to fig1 thereof , there is seen an embodiment of an apparatus according to the invention , in the form of a single - side web - up device , for attaching a web of material for translation through a rotary printing press system . the apparatus includes a triangle or kite 1 which is attached to a web 3 and to a guiding device or snake 2 . the triangle 1 shown in the overall view of fig1 is attached to the guiding device 2 in such a way as to provide translation in a direction of travel indicated by an arrow , as well as to provide support for the web 3 . a stiffener pad 4 provides the support across the web and acts as an attachment interface of the triangle to the web . fig2 shows a reinforcement orientation of the triangle 1 which is used to describe a parallel and perpendicular lay of a mat material . the triangle 1 is formed of a woven mat . the mat has a parallel weave 5 and a perpendicular weave 6 , as oriented relative to the hypotenuse 7 of the triangle , for a distribution of loads 8 from web tension . the mat may be formed of a fiberglass material such as that sold under the trademark fiberglas . fig3 a shows details of triangle stiffener and attachment configurations . the triangle 1 and the web 3 are interconnected by the stiffener pad 4 . the pad 4 is joined to the triangle 1 by an adhesive and / or by stitching 9 . the web 3 passes through a slot 10 to secure the web to itself with adhesive tape 11 . the slot 10 is shown without the web in fig3 b . fig3 c shows that the slot 10 has an edge piece 12 of a rounded material to prevent the web from severing due to the thin nature of the stiffener pad 4 . fig4 a shows a post and grommet configuration 13 for attachment of the triangle 1 to the guiding device 2 . the triangle 1 is attached to the guiding device 2 along the length of the triangle . as is best seen in fig4 b , a grommet 14 is slipped over a post 15 in such a way that the post captures the grommet . fig4 c shows that the post 15 has a lip 16 facing in the direction of web travel that acts to retain the grommet 14 and prevent the triangle 1 from stripping off of the guiding device 2 . however , the structure of the post 15 allows easy removal of the triangle . fig5 shows a zipper configuration for attachment of the triangle 1 . a zipper 17 shown in the figure has the same function as the post and grommet configuration . the zipper 17 is attached to the guiding device 2 and to the triangle 1 by adhesive 18 and / or by stitching 19 . it is understood that the location of the adhesive 18 and the stitching 19 relative to the zipper 17 may be the opposite of that shown . furthermore , both attachments may be adhesive or both may be stitching . fig6 a illustrates an attachment of the triangle or flexible kite 1 to the web 3 by using a clamping bar configuration 20 . fig6 b shows that the clamping bar configuration includes two clamping bars 21 and 22 , between which the triangle 1 and the web 3 are clamped . the clamping bars 21 , 22 may be held together by screws 23 and / or clips 24 which may be recessed or disposed in grooves . according to fig6 c , the clamping bars 21 , 22 may be dome - shaped . fig7 a shows the triangle and the guiding device , snake or train in a side view . a post actuation device is provided in order to attach the triangle 1 to the guiding device 2 without having to place each grommet 14 over a respective post 15 . the post actuation device includes a triangle guide 25 and a train guide 26 for attaching the triangle 1 to the guiding device 2 . as is seen in fig7 b , the triangle guide 25 orients the grommets 14 perpendicular to the posts 15 in such a way that the shanks of the posts 15 are able to pass through the eyes of the grommets 14 . the figure also shows that the train guide 26 acts to maintain the orientation of the guiding device 2 while this action is taking place . a post 15 is able to pass through a slot 27 in the triangle guide 25 , which is seen in fig7 c and 7 d . after the post 15 has passed through the eye of the grommet 14 , the triangle 1 and the guiding device are aligned in parallel to lock the grommet 14 onto the post 15 . this prevents separation of the two components during subsequent travel of the combination .
