Definitions

• the invention relates to a cloth towel dispenser with two abutting towel units, each of which towel unit has a housing with a lid, a dispensing point with a dispensing roller for receiving and for unrolling sections of a clean towel roll and a draw-in point with a feed roller for pulling in and winding up the used towel part has a wrap and can be used for manual drying by pulling out a towel loop, the output roller being connected to the feed roller via a gear and on the underside of the housing there is a signal flap which is pivotally mounted in the side walls of the housing and which, in the visible position, indicates the readiness for use of the one towel unit .
• Towel dispensers in which a piece of fabric is provided to dry the hands are known in various designs. With most towel dispensers, the user has to pull a piece of cloth out of the dispenser with which he can dry his hands.
• the cloth towel is a band of finite length, which is available for a certain number of uses and then has to be replaced. So that the resulting interruption in use can be bridged, it is known from EP-A-0 283 554 by the applicant to use a towel dispenser consisting of two adjoining towel units.
• the two towel units of this dispenser which is referred to as the twin dispenser, are of exactly the same design. Your cloth towel is fed into a feed roller via an output roller.
• the feed roller When the towel is pulled out to form a towel loop, the feed roller is rotated along with an enveloping drive.
• a spring force accumulator is arranged in the feed roller and is pulled up each time a towel loop is formed.
• the length of the pull-out towel is limited by a lock.
• the pull-in roller After a towel loop has been pulled out, after a certain period of time, the pull-in roller is set in rotation by the spring energy storage device and the towel loop is thereby wound on it so that the loop used disappears.
• This well-known twin donor works reliably.
• the second towel unit As soon as the cloth towel of one towel unit has been used up, the second towel unit is released for operation by pivoting its signal flap into the visible position.
• the towel unit with the used cloth towel can be exchanged and made available during the operating period of the second towel unit, so that after the cloth towel in the second towel unit has been used up, the first towel unit is ready for operation again.
• a towel loop can also be pulled out for use with the other towel unit provided with a towel, although in this the signal flap is in non-visible position and only pivots into the visible position after the cloth towel of a towel unit is used up and rolled up on the feed roller.

Furthermore, a signal flap 10 is visible on the underside, which, in the visible position shown, enables the clean towel fabric to be pulled out and draws attention to the refilling of the fabric when the fabric reserve is used up.
• A is an output point for receiving a clean towel roll 15 and E denotes a draw-in point below the output point A for picking up and rolling up the used towel roll 16.
• the clean towel roll 1 5 lies in a winding tray 18 which can be pivoted about an axis 17 and which is pulled upwards by spring force (not shown), insofar as the winding 15 permits this.
• the cloth towel 7 dispensed by the winding 15 is guided over the free edge 19 of the winding shell 18 around a delivery roller 20 provided with a rough circumference and then over a pressure roller 22, whereupon the cloth 7 is descending within the cover to the signal flap 10 (in FIG. 2 not shown) and then extends up to Einzugstel le E.
• the hands are dried after the loop 8 has been pulled out.
• the shell 18 can be pulled down using a grip tab 105 (see FIG. 9).
• the used cloth towel is guided over a likewise provided with a rough surface feed roller 25, on which the used towel roll 1.6 is wound up on a mandrel 26 which is guided in a guide groove 70 arranged in the housing walls 11, 12 and can thereby evade according to the growing diameter of the winding 16.
• the pressure roller 22 in the delivery point A is guided in guide slots 28;
• the result of the cloth guide is that when the loop 8 is formed, the output roller 20 is pressed and reliably set in rotation.

• This can be accomplished in a simple manner by means of a square tube, which at the end of the signal valve shaft 67. is arranged and is pushed onto a square of the signal valve shaft of the abutting towel unit. A further connection to the towel unit 3 is not necessary.
• Both the towel unit 2 and the towel unit 3 can be operated on their own. Only the cover in question is to be used. These covers are only to be replaced by the transition frame 4 and the coupling of the two signal valve shafts 67 is to be carried out simultaneously with the connecting pipe if the arrangement is common.

• the signal flap 10 indicates the operational readiness of the towel units 2, 3 or the end of the fabric feed on the feed roller 25 practically independently of the other function of the twin dispenser. If the one towel unit is in operation, the signal flap is in the visible position. In the other towel unit, the signal flap 10 is in the non-view position, see towel unit 3 in FIG. 1; the towel unit is ready for use. It is now essential that the towel unit can be used even in this state, although the signal flap 10 is not visible. The signal flap 10 swung out in the towel unit 2 thus draws the user's attention to using the towel unit with the visible signal flap. As a result, the towel unit with the signal flap not swung out remains in.
