DE1511440A1 - Automatic clamping device for tearing off paper with automatic release - Google Patents

Description

Title: Automatic clamping device for tearing paper with automatic Disminning.

Application The invention relates to the separation of area: on rollers wrapped paper.

E.g. for wrapping paper, toilet paper and the like.

Purpose: To tear off a piece of paper from a roll.

State of the art It is known to fulfill this on-technique: gave the To attach the paper roll so that it rotates. Now a piece of desired becomes Unrolled length and this over. a tear strip or by means of a knife or separated at the perforation.

Criticism of this often occurs that the state of the the roll rotates when it is separated and technology: it either turns the paper not at all, or only very poorly and mostly at an angle. Also needed you always have both hands.

Task: The invention is based on the task of slipping To avoid tearing the paper while tearing it off, use one hand as well and to be able to continue unwinding the paper effortlessly after it has been separated.

Solution: This object is achieved according to the invention in that a clamping device automatically clamps the paper during cutting and this clamping is automatic after the separation during further unwinding of the paper is resolved.

Further So that the paper doesn't suddenly run out of design can, a reserve winding is inserted into the cardboard ring of the Pader invention: pier roll.

Description An embodiment, example of the invention is an embodiment shown in the drawing and is described in more detail in the example below. 1 shows the paper roll (1) lying loosely in a container (2). For heavier ones Roll paper (1) can also be rotatably mounted on the same channel. The paper (3) of the Paper roll (1) is now pulled in direction (4) and unwound on the desired line.

Fig. 2 now the paper (3) is pulled in direction (5). This jammed the paper (3) is wedged between the curve (6) on the container (2) and the curve (7) on the cover (12). The lid (12) is rotatably mounted on the container (2) in Pullkt (15). The harder you pull on the paper (3) in direction (5), the more firmly it jams due to the wedge effect of the two curves (6) and (7).

The paper (3) can still be clamped by two rubber strips (8) be reinforced on curve (6) and a rubber strip (9) on curve (7). The paper (3) can now be easily removed with one hand on the friction strip (10).

Fig. 3 the spring (11) now lifts the remaining piece of paper (3) between the curves (6), (7) and tear strip (10) ant so that it can be easily grasped can.

Fig. 1 now the paper (3) is pulled in the direction (4). Through this the cover (12) rises and the clamping is released. The paper (3) can again can be unwound to the desired length from roll (1).

The reserve paper can be in the form of a reserve winding (13) inside of the cardboard ring (14) of the paper roll (1).

Achievable The advantages achieved with the invention be advantages: are particular in that each paper is easily unwound from the roll and in each the desired length can be easily cut off.

For example, when this invention is applied to toilet paper, it is needed you no longer have to use both hands to separate a piece of paper from the roll, as before, but can do this easily with one hand.

Due to the reserve winding inside the @ paper roll, the paper can never go out unexpectedly.

In addition, the paper roll is in a closed container, which is significantly more hygienic.

Claims (1)

Claims: Generic term: For cutting off what is wound on rolls Paper, characterized by the fact that the paper at the part: Separate is automatically clamped and when it is further unwound from the roll, the Paper disengaged automatically. Generic term of reserve paper, @nt er claims: Characteristic thereby characterized that a reserve part of the winding inside the cardboard ring of the Pa-subclaim: pier roll is attached.
