Abstract
Apparatus 10 for dispensing paper from one of different width rolls 4, 5 and 6 includes a movable arrangement 11 associated with each roll, each arrangement supporting and unwinding a roll of adhesive tape 20 and applying the tape to one edge of the paper as it is unwound. The arrangement 11 is constructed such that the width 39 of the adhesive tape directly stuck to the paper depends neither on the width of the paper nor the width of the adhesive tape. Uprights 9 support the rolls on spindles such as 7 inclined to the horizontal. Each arrangement 11 has a bar 12 resting on its associated roll with a guide 21 contacting an end face of the roll, and pairs of guide brackets 17 freely engaging respective uprights 9 between them. The arrangement 11 has paper cutting teeth 18 and a plate 19 supporting a roll 20 of the adhesive tape between small rollers respectively inside and outside the roll 20 and supported on the plate. Tape unwound from roll 20 goes round the back of the outside roller. The plate 19 is inclined in the same direction as the paper roll but at a greater angle to the horizontal and is carried by a plate 32 supported on a plate 33 on frame 11. The plate 32, and therefore the plate 19 and roll 20, can be pivoted away from plate 33 by adjusting screw 38 to control how much of tape 3 extends beyond the edge of the paper sheet. <IMAGE>
Description
SPECIFICATION
Distributor for paper having an adhesive edge, in particular for painters and body-builders
The present invention relates to a distributor for paper having an adhesive edge, in particular for painters or body-builders.
It is known that before proceeding with painting operations proper, painters cover or mask certain surfaces which are not to be painted, above all when the paint is applied by means of a spray gun, which is the case when carrying out bodywork. To do this, painters use sheets of paper which they stick by means of adhesive tape overlapping the edges of the sheets of paper. When it is necessary to carry out this operation without the assistance of any appliance, a great deal of time is lost and relatively wide adhesive tapes must be used in order to compensate for irregularities in the relative positioning of the adhesive tape and of the edge of the sheets of paper.
The invention intends to simplify the masking operation considerably by providing a distributor which is capable of supply directly webs of paper together with adhesive tapes which are already in position.
The invention also intends to make a saving as regards the consumption of the adhesive product, by making it possible to use much narrower adhesive tapes owing to greater accuracy in the relative positioning of the adhesive tapes and of the edge of the sheets of paper.
The invention also intends to provide a distributor which can be used with sheets of paper of varying widths and with which it is possible to change from one width to another without adjustments.
According to the invention there is provided distributor apparatus to distribute sheets of paper together with an adhesive tape overlapping one of their edges, comprising a frame provided with at least one spindle on which a roll of paper is able to rotate, said spindle being surmounted by a movable arrangement which supports means for unwinding adhesive tape and which is mounted in order to bear permanently on the roll of paper by means of a contact shoe in order that the adhesive tape is guided on the upper edge of the roll of paper as it unwinds, said spindle and an unwinding plate supporting rollers for guiding the adhesive tape and supporting a roll of adhesive tape by one side edge being both inclined downwards at the side where an abutment bearing against the upper edge of the corresponding end face of the roll of paper is provided on the movable arrangement, this double inclination ensuring, by gravity, automatic relative positioning of the paper and of the adhesive tape, and this relative positioning being independent of the relative widths of the sheet of paper and of the adhesive tape.
The contact shoe can be constituted by a bar, the ends of which are located, on the movable arrangement, in the immediate vicinity of slides arranged to move along vertical uprights of the frame, these same uprights being integral with bearings supporting the ends of the spindle on which the corresponding roll of paper may rotate.
At each end of the bar, the movable arrangement can comprise a substantially horizontal cross-bar, the front ends of the two cross-bars being connected to each other by a rectilinear bar having a lower cutting edge.
The respective inclinations of the spindle on which the roll of paper is mounted in order to rotate and of the unwinding plate can be respectively of the order of several degrees and of the order of approximately thirty degrees with respect to the horizontal.
The unwinding plate can support two guide rollers, namely: - a first roller located exactly at the rear of the active end of the abutment of the movable arrangement; -a second roller, which is offset in a forwards and upwards direction with respect to the first roller and which has an outer diameter considerably less than the inner diameter of the roll of adhesive tape;
so that the adhesive tape coming from the roll threaded around the second roller passes behind the first roller with which this adhesive tape is in contact by its non-adhesive side, in order to be guided towards the corresponding upper edge of the roll of paper.
The spindle of the second roller may be slightly more inclined than a line perpendicular to the unwinding plate starting from the base of the axis of the second roller, this axis and this perpendicular line together forming an angle of several degrees of a vertical plane parallel to the axis of the roll of pauper.
The axis of the first roller can extend upwards moving away slightly towards the rear from a line perpendicular to the unwinding plate starting from the base of the axis of this first roller, this axis and this perpendicular line together forming an angle of several degrees in a plane which meets the unwinding plate along a horizontal line.
The attachment of the unwinding plate to the movable arrangement can be ensured by means of two small plates whereof the major faces are substantially vertical and whereof the major axes are substantially parallel to the cross-bars of the movable arrangement, the first small plate being integral with the unwinding plate and the second with the movable arrangement, a coil spring being compressed between the outer face of the first small plate and a nut screwed onto the free end of a bolt which passes with considerable clearance through a hole in the first small plate, the head of this bolt bearing against the outer face of the second small plate, whereas at a distance from the bolt and to the rear of the latter, this second small plate comprises on the one hand a support plate which supports the first small plate by its lower edge and on the other hand a tapped hole which receives an adjusting screw, the free end of this adjusting screw being in abutment against the inner face of the first small plate in order to adjust the value of the acute angle formed by the inner faces of the small plates.
The invention will now be further described, by way of example, with reference to the accompanying drawings, in which: Figure 1 is a general perspective view of a distributor apparatus formed according to the invention;
Figure 2 is a perspective view solely of the movable arrangement;
Figure 3 is a partial side view of the distributor;
Figure 4 is a partial plane view of the distributor;
Figure 5 is a partial rear view of the distributor;
Figure 6 shows an enlarged portion of Figure 3; and
Figure 7 is a view in direction VII (Figure 5).
Figure 1 shows a distributor according to the invention, which is intended to distribute sheets of paper 2 together with an adhesive tape 3, the tape 3 being arranged to overlap one longitudinal edge of each web of paper. This distributor is capable of distributing sheets of paper from three different rolls of paper 4, 5 and 6, which makes it possible to have three different widths of paper permanently available. In the following description, we shall deal solely with the members of the apparatus associated with the roll of paper 4, it being understood that the same arrangements are provided for the rolls 5 and 6.
The roll of paper 4 is mounted in order to rotate on a spindle 7, the ends of which are supported by
bearings 8 integral with uprights 9 belonging to the frame 10 of the distributor.
The spindle 7 is surmounted by a movable
arrangement 11 composed of a bar 12, a front
rectilinear bar 13 and two lateral cross-bars 1 5 and 1 6. The bar 12, which always remains parallel
to the spindle 7 during operation, acts as a contact
shoe always remaining in contact with the roll of
paper 4 along one generatrix of the latter. The
ends of the bar 12 are located on the movable
arrangement 11 in the immediate vicinity of slides
17 mounted to move along vertical uprights 9 of
the frame 10. The cross-bars 15 and 16 are
substantially horizontal and the front rectilinear
bar 1 3 is provided with a lower cutting edge 1 8.
In its rear part, by means of an unwinding plate
19, the movable arrangement 11 supports a roll of
adhesive tape 20 from which the adhesive tape 3
is unwound, whereas the cross-bar 1 6 is integral
with an abutment 21 intended to bear against the
upper edge of the corresponding end face of the
roll of paper 4.
The following geometric features will be noted,
which are of essential interest for the operation of
the distributor: - the spindle 7 is inclined slightly downwards
adjacent the cross-bar 1 6, in order to form an
angle 22 of several degrees with respect to the
horizontal (Figure 5).
- The unwinding plate 1 9 is inclined considerably downwards adjacent the cross-bar
1 6, in order to form an angle 23 of approximately thirty degrees with respect to the horizontal.
The unwinding plate 19, which supports the roll of adhesive tape 20 by one side edge, supports guide rollers 24 and 25. The roller 24 is located exactly at the rear of the active end of the abutment 21. Its axis 26 extends upwards moving' away slightly towards the rear from a line 27 perpendicular to the unwinding plate 19, starting from the base of the axis 26, this axis and this perpendicular line together forming an angle 28 of several degrees in a plane which meets the unwinding plate 1 9 along a horizontal line. The roller 25 is offset in a forwards and upwards direction with respect to the roller 24.Its axis 29 is slightly more inclined than a line 30 perpendicular to the unwinding plate 1 9 starting from the base of the spindle 29, this axis and this perpendicular line together forming an angle 30a of several degrees in a vertical plane parallel to the spindle 7.
The rollers 24 and 25 have the same outer diameter, which is clearly less than the inner diameter 31 of the roll 20 of adhesive tape.
The attachment of the unwinding plate 1 9 to the cross-bar 1 6 is ensured by means of two small plates 32 and 33 respectively integral with this plate and this cross-bar. These two small plates are substantially parallel to the cross-bars 1 5 and 1 6 and their major faces are arranged vertically.
A bolt 34 is engaged in the front end of the small plate 33. The head of this bolt is locked against the outer face of this small plate, whereas the shank of the said bolt passes with considerable clearance through a hole provided in the front end of the small plate 32 in order to receive a nut 35 at its free end. A coil spring 36 engaged around the bolt 34 and compressed between the outer face of the small plate 32 and the nut 35 permanently tends to bias the opposing inner faces of the small plates 32 and 33 towards each other. At its rear end, the small plate 33 comprises on the one hand a lower support plate 37 on which the lower edge of the small plate 32 bears and on the other hand a tapped hole in which an adusting screw 38 is screwed.The free end of this adjusting screw bears against the inner face of the small plate 32 in order to space the two small plates apart by an acute angle 39, the value of which may be varied by rotating the adjusting screw 38.
The operation is as follows:
At the time of setting the apparatus in operation, the roll of adhesive tape 20 is threaded around the second roller 25 and the adhesive tape is arranged so that as it leaves the roll 20, it passes to the rear of the roller 24 with which it isZ intended to be in contact by its non-adhesive side in order to be guided towards the corresponding upper edge of the roll of paper 4.
The width 39 of the area of adhesive tape directly stuck to the sheet of paper depends solely on the adjustment of the screw 38 and it thus depends neither on the width 40 of the sheet of paper, nor on the width 41 of the adhesive tape. In fact, the width 39 is controlled automatically by the support of one side edge of the roll 20 on the unwinding plate 1 9 and by the support of the end face of the roll 4 on the abutment 21, these two supports being achieved simply by the effect of gravity. It will be noted that possible irregularities in the winding of the adhesive tape or in the winding of the sheet of paper (in certain cases due to dropping of the rolls during various handling operations) are automatically compensated for and have no effect on the width 39.
The bar 12 by means of which the movable arrangement 11 rests by its full weight on one generatrix of the roll 4 serves to slow the latter down, in order to prevent the latter from continuing to unwind solely by the effect of inertia when the user is no longer pulling on the paper.
By simply pulling on the paper, the user is able to obtain a sheet of paper of the desired length, bordered by adhesive tape and constituting masking material ready for use. After having withdrawn the desired length of paper, the user exerts a sharp upwardly directed pulling action on the paper which is suitable to bring about cutting of the paper along the cutting edge 1 8 with which the bar 13 is provided.
The apparatus according to the invention in particular has the following advantages: it makes the masking operation much quicker by eliminating manual positioning of the adhesive tape on the edge of the sheets of paper.
It makes it possible to achieve a substantial saving as regards the consumption of adhesive products by a strict control of the width 39, this control making it possible to use much narrower adhesive tapes than previously.
In the preceding description it will be understood that we have envisaged solely the use of rollers 24 and 25 provided with lateral surfaces which are cylinders of revolution. One could equally well use rollers having a frustoconical lateral surface by arranging the axes of these rollers at right angles to the unwinding plate 19, the flared ends of the rollers being directed upwards for the roller 24 and downwards for the roller 25. From the point of view of operation, this arrangement is fully equivalent to the former, since the generatrices of the rollers have substantially the same orientations as previously in the areas of contact with the adhesive tape. The result obtained is the same, which consists of always keeping one of the edges of the adhesive tape pressed against the upper surface of the unwinding plate 1 9 under the effect of the various reaction forces exerted by the rollers on the adhesive tape during the forwards movement of the latter.
