DE3504688A1 - Apparatus for sticking webs of paper together - Google Patents

Abstract

Called a connecting apparatus for short hereinafter, this apparatus is an everyday aid for sticking together webs of paper (EDP sheets, fold-stacked, or forms and labels on rolls for example). These so-called "endless forms" are printed in programmed printers, in which they have to be threaded, aligned and printed with data. The webs of paper do have an end, however, and pass through the printer. The connecting apparatus serves to save the time taken by rethreading and to avoid losses of sheets due to alignment and make reprogramming of the printer unnecessary. By ensuring that e.g. the end of roll I is stuck to the start of roll II, the end of roll II is stuck to the start of roll III etc. in good time, the user will save significant costs. Under certain conditions, the connecting apparatus will save considerable expense and downtime associated with programmable printers and will pay for itself, owing to its rational and uncomplicated mode of application.

Description

Device for gluing together paper webs

The device is initially used for quick and easy assembly of paper web ends. However, economic considerations are more essential than that To see advantage.

Paper webs (EDP sheets or forms), packed in folding layers in the box, are sent to printers stored with specific, recurring data threaded.

The onward transport of the paper web is therefore carried out automatically. Will does not end in time with the beginning of a new paper web (in the box folded and stacked as many as desired standing one behind the other on the floor) connected, so runs through the end of the first paper web the printer and in The programming is usually deleted and has to be recreated.

Due to this fact, there are always several start or end leaves no longer to be used. Whereby the re-threading together with the re-programming also causes costs. These points already speak for the advantages of the ones described Contraption.

Depending on the function (together with the device), an adhesive film is required rolled up with a central predetermined breaking point (8) which runs parallel to the edge of the tape used as a roll (3) with a tape length of approx. 90 m. Depending on the width of the to be connected Leaves this results in several hundred connections, in the present case about 375.

The tape guide can therefore not be done often and is also easy to create. The glue roll (3) is placed in the circular recess (9). The beginning of the new roll stiffened by red cardboard snippets is placed on the guide pin (10). The device is now turned. The roller (3) is to be held in the recess (9), or a rubber band (7) is conveniently placed on it. The beginning of the roll (3) is pulled around the deflection pin (10), then the tape is pivoted through 900 in its longitudinal axis (4) so that the adhesive side faces the viewer, then passed through the slot (11). The beginning of the tape (18) protruding to the side of the device (dash-dotted line) will stick to the pins (12) by pressing it lightly. The device is turned back into the normal position and towards the two (mentioned at the beginning) Laying a stack of sheets. While the device is held in place with one hand to prevent it from slipping sideways, the thumb and forefinger of the other hand grasp the adhesive tape (18) protruding from the side of the device and pulls it, deflected over the guide pin (13) in the indicated direction of the adhesive tape ". It is pulled for as long until enough tape protrudes over the edge of the device to be able to loop around the two deflection pins (14, 15). Since the adhesive side of the tape is functionally turned away from the base body (1), the end (16) sticks securely due to the partial looping of ( 15).

The roller (3) rotates independently during the process just described, accordingly provides correct resistance to unwound tape in the entire area keep tense (4 to 16). The two deflection pins (13 and 14) are in diameter rotated somewhat weaker according to the bandwidth, around the tape in the Y-plane to give the center guide. Deflection pin tal4) is correspondingly longer than pin (15), so that when wrapping from (15) to (14) the band is laterally displaced can be in order to be able to wrap around (15). Now the end of a leaf Stack, with the help of the guide pins (6), placed on the device so that hit the edges above the predetermined breaking point (8). With fingertip or thumb on vigorously over the seam (8), this is sufficient for the printing process secure connection of the two guaranteed for the later desired separation Leaves. The rubber bands (7) are used to hold down the leaves.

A simple but safe separation of the tape is achieved by pressure reached with the tip of your finger or thumb (17) in the depressions (5). The at the Assemble part (2) between this and the base body (1) inserted knife, cut the tape exactly on the edges of the sheet. The risk of injury is practical excluded because the knife edge does not protrude from the device.

Automatically after the cutting process, due to the spring action of the adhesive tape, the freed ends spring outwards, whereby the re-used end (18) stops automatically at (12) and remains within reach.

Excess (16) at 14/15) is pulled away and is less Waste.

Suspension pins (19) for the rubber bands (7) have a further purpose. The sheets to be printed and connected are usually stored in cardboard boxes, which have the clear width of the leaf width. If the device is now on two If the boxes are not completely full, these cannot be put in one or the other box tilt in, as the support pins (19), which are far from the center of the device, support on the cardboard walls (see sketch II)

Claims (5)

Claim sketch I device for gluing together paper webs, consisting of a base body (1), the two deflection blocks (2) and various Guide or guide pins (6, 10, 12, 13, 14, 15). The base body (1) has recesses for inserting and guiding the adhesive roll (3), the tape unwinding (4). as well as the Function of the cutting process at (5,17). 2. Device according to claim 1, characterized in that the base body (1) in width corresponding to the width of the paper web to be connected (EDP sheets) is made. 3. Apparatus according to claim 1, characterized in that according to the edge perforation of the paper web, equally spaced, on the two Sides of the base body (1) tapered guide pins (6) are to to ensure the exact alignment of the sheets to be joined. 4. Apparatus according to claim 1, characterized in that when Place the end of the paper web and the beginning of the new paper web, the guide pins (6) the two paper web ends parallel and flush in the middle of the base body (1) fix exactly over the predetermined breaking point (as described later in the description) (8) of the applied adhesive film. Two endless rubber bands (7) are used for Holding down the placed and to be connected sheets (paper web ends) on the 6 round body (1). Sketch II 5. Apparatus according to claim 1, characterized in that that this does not tip over, due to the commercial type of packaging of the paper webs (EDP sheets), lying flat on the cardboard edges, can be used without any problems can.
