Abstract

A laminate stripping device comprises a body (12, 14) having a recess (16) arranged to receive a corner of a laminate (22) from which the release layer (26) is to be stripped, and a blade (20). The depth of the recess is such that the interface between self-adhesive layer (24) and the release layer (26) is below the surface of the body so that on passing the blade (20) over the surface of the body it will contact the self-adhesive layer (24) only, to lift it and allow it to be gripped. <IMAGE>

Description

A LAMINATE STRIPPING DEVICE This invention relates to a laminate stripping device and is particularly though not exclusively concerned with stripping the release film or paper from a self-adhesive photocopiable drafting film.
Some release films or papers on self-adhesive photocopiable drafting film are back slit to enable the release film to be removed once the laminate has been photocopied. However, in the case of back slit release films or papers the slit shows up as a thin line on the photocopied drafting film. Therefore there are many instances where the release film or paper cannot be back slit and it has to be removed from the drafting film by hand using a thumb or finger nail. Such an operation is time consuming and can damage the drafting film.
The present invention seeks to provide a stripping device to enable at least a portion of the self-adhesive film to be lifted from the release film or paper so that the remainder of the selfadhesive film can be removed after the laminate has been photocopied.
Accordingly the present invention provides a laminate stripping device comprising a body and a blade, the body having a recess arranged to receive a corner of the laminate comprising a self -adhesive film or paper and a release layer, the depth of the recess being such that the self-adhesive film or paper is proud of the surface of the device when the laminate is placed in the recess, and the release layer can be stripped from the selfadhesive film or paper by passing the blade over the surface of the body so that the blade contacts the self-adhesive film or paper only.
An adhesive pad can be located in the recess so that the laminate can be fixed in position relative to the body of the stripping device.
The body can comprise two layers of plastics material secured together, the upper layer having a triangular portion removed to form the recess.
The two layers of plastics sheet material can be oblong and the recess can be formed on one of the short sides of the oblong.
The blade can comprise a portion of plastics sheet material.
The present invention will now be more particularly described with reference to the accompanying drawing in which, Fig. 1 shows a plan view of one form of laminate stripping device according to the present invention, Fig. 2 shows a section on line 2-2 in Fig. 1 together with the blade and a portion of laminate to be stripped and Fig. 3 shows a portion of the laminate in position relative to the stripping device.
Referring to the figures, a laminate stripping device 10 comprises two layers of plastics sheet material 12 and 14, the layer 14 having a triangular portion removed to create a recess 16.
Located in the recess in the apex of the triangular recess is an adhesive pad 18.
As shown in Fig. 2 the stripping device also includes a blade 20, the function of which will be described below. A laminate 22 comprises a layer of self-adhesive film or paper 24 to which printing has been applied on the surface 24A and a release layer 26 which can be a film or paper.
Once printing has been applied to the surface 24A, it is then required for the release layer 26 to be removed so that the selfadhesive film or paper can be secured in place by the layer of adhesive lying underneath layer 24.
As shown in Fig. 3 a corner of the laminate 22 is placed in the recess 16 and is held in position by the adhesive pad 18. The depth of the recess is chosen such that the self-adhesive layer 24 is proud of the surface of the device but the layer of release film or paper lies beneath the top surface of the stripping device. The blade 20 is then passed over the top surface of the body 10 so that it contacts the self-adhesive layer 24 but not the release film or paper and lifts a portion of the self-adhesive layer from the release film or paper so that the lifted portion can be gripped between two fingers and the whole of the selfadhesive layer peeled from the release film or paper. Preferably the blade has a bevelled edge as illustrated.
The laminate stripping device according to the present invention allows laminates to be stripped easily and rapidly without causing damage to the drafting or any other film or paper from which a release layer has to be stripped.

Claims (6)

1. A laminate stripping device comprising a body and blade, the body having a recess arranged to receive a corner of a laminate comprising a self-adhesive film and a release layer, the depth of the recess being such that the self-adhesive layer is proud of the surface of the body and can be stripped from the release film or paper by passing the blade over the surface of the body so that the blade contacts the self adhesive layer only.
2. A device as claimed in claim 1 in which an adhesive pad is located in the recess to fix the laminate in position.
3. A device as claimed in claim 1 or claim 2 in which the body comprises two layers of plastics sheet material secured together, the upper layer having a triangular portion removed to form the recess.
4. A device as claimed in claim 3 in which both said layers are oblong and the recess is formed on one of the short sides of the oblong.
5. A device as claimed in any one of the preceding claims in which the blade comprises a portion of plastics sheet material, one of the edges of which is bevelled.
6. A laminate stripping device constructed and arranged for use and operation substantially as hereindescribed, and with reference to the accompanying drawings.
