The slot extends the entire length of the drum. The attachment means permits the attachment strip to be inserted in the longitudinal direction into the receiving means. At least one end wall of the housing has an insertion opening extending from an end of the first opening in the housing. The insertion opening is in the form of a slot and is arranged with respect to the drum such that the attachment strip can be brought into engagement with the receiving means on the drum by inserting the attachment strip through the insertion opening in a direction substantially parallel to the longitudinal axis of the drum.

[0004] GB 2 474 582 A describes a banner system comprising a roller mounted within a base unit and a banner releasably rolled around the roller. A width of the banner is the same as a length of the base unit. At least one end of the base unit is provided with an engagement means, whereby it can be attached to a second banner system. The base units may be held together magnetically. For providing a display comprising two banner systems, the individual banners are rolled out into viewing position, and the neighboring banner units are then assembled together.

[0005] The Chinese utility model No. 200620047999.6 discloses a display shelf named "roll-up graphic display shelf frameless in a front view and achieving gapless graphic assembly", which includes a housing, a flip cover, a clamping mechanism and a supporting foot, where the front portion of the display shelf is an isosceles trapezoid that is short at the front and long at the back, the front edge and the graphic are equally wide, the flip cover is inserted, by a connecting shaft provided at the rear end, into shaft sleeves provided on inner sides of two housing end covers, to be connected to the housing, the housing and the interior of the flip cover form a cavity, and a gap through which the graphic passes is left between the front edge of the flip cover and the housing. If a plurality of the roll-up graphic display shelves are placed end to end, a seamless assembled graphic wall can be formed, and the graphics form an angle not greater than 150° therebetween. Although seamless graphic assembly can be achieved by assembling the display shelves with the above structure, the assembled large graphic is not a plane and there is no connection between the display shelves; as a result, in applications, consistency of the graphic may be damaged due to separation between the display shelves.
