Definitions
- the invention relates to a device for applying a closing strip, which device comprises for this purpose a box ⁇ like housing profiled with a channel,
- a first part of the housing bounded by the channel is provided with a first drum-shaped space for storing adhesive tape, with first through-feed means for feeding a strip of adhesive tape from the drum-shaped space to the channel, and with a rotor having fins protruding into the channel for further guiding said strip of adhesive tape into the channel with the sticking side facing outward;
- a second part of the housing bounded by the channel is provided with a second drum-shaped space for storing tape ⁇ like material, with second through-feed means for feeding a strip of tape-like material from the second drum-shaped space to the channel,
- the edge side, located on the access side of the channel, of the second part of the housing bounded by the channel is at least partially formed by removably embodied closing means which closes the second drum-shaped space and which in the closing position co-acts form-fittingly with a bridge piece situated in the second drum-shaped space in order to obtain said second through-feed means for placing in a clamping position a strip of tape-like material present at that position.
- fig. 1 shows a perspective view of a first embodiment of the device for applying a closing strip
- fig. 2 shows a partly cut away and broken away front view of the device shown in fig. 1
- fig. 3 and 4. show two different positions of use of the device depicted in fig. 2 during applying of a closing strip
- fig. 5 and 6 show a section of a part of the device for applying a closing strip, wherein the closing means are respectively situated in folded-down position and pivoted outward through a certain angle
- fig. 7 shows a second embodiment of the device for applying a closing strip
- fig. 8 shows a possible embodiment of an element of the device for applying a closing strip
- fig. 9 shows a portion of a sub ⁇ eguent possible embodiment of a device for applying a closing strip.
- Shown in fig. 1 is a possible embodiment of a device for applying a closing strip round an enclosure 2 such as a twisted together end of a plastic bag.
- the device can be divided into a housing 1 in box ⁇ like form with means for applying the closing strip, and a base plate 3 positioned perpendicularly of this housing 1.
- Housing 1 comprises two side surfaces 4 and 5 and is further provided with a channel 6, which roughly divides each of the side surfaces 4 and 5 into two equal box portions 7 and 8 and which forms the path of movement for the enclosure 2 to be girded with a closing strip.
- channel 6 is embodied over practi ⁇ cally the whole length as a straight gap, which implies the advantage of an easier running guiding for enclosure 2.
- These blades 11 guide a strip of one-sided adhesive tape 12 supplied from the box portion 7 via guide means to the channel 6, wherein the adhesive tape will adhere to a large portion of the surface of the enclosure 2.
- the channel 6 embodied substantially as straight gap has the result that, when the enclosure 2 is introduced into channel 6, the enclosure 2 is carried deeply into the opening between two successive blades, whereby enclosure 2 is covered with the adhesive tape 12 over a large part of the periphery.
- the blades 11 are herein dimensioned such that it is impossible for the enclosure 2 to be carried downward past the outside of the blades 11, whereby insufficient adhesive tape would be able to engage onto enclosure 2.
- the strip of adhesive tape 12 comes from a roll or a reel 13 situated in a hollow space 16 of box portion 7. When the roll or reel 13 can rotate on a hub or shaft 15, channel-like guide means 14 are arranged for this purpose in box portion 7.
- a rubber ring can also be arranged round the shaft 15 with which reel 13 makes frictional contact with the channel-like guide means 14 and whereby free turning and thereby undesired unwinding of adhesive tape 12 from the roll or reel 13 is avoided.
- the rotor 10 can further be advantageously provided with clamping means (not shown in the figure) such as a clamping spring arranged over the rotor shaft, whereby rotor 10 is not permitted any free rotational movement.
- clamping means such as a clamping spring arranged over the rotor shaft, whereby rotor 10 is not permitted any free rotational movement.
- another strip of tape-like material such as paper tape 17
- the strip of paper tape 17 is supplied from another reel or roll 18 which is stored in a drum-shaped space 34 present in the other box portion 8.
- the peripheral surface of box portion 8 connecting onto the access side of channel 6 is embodied closably using a folding or closing cover 35 acting as closing means.
- the point of rotation of folding cover 35 may be located in this part of the peripheral surface of box portion 8 as well as in the adjoining side face.
- Cutting means 20 comprise in this embodiment a member 21 embodied as a knee lever which is ar ⁇ ranged for rotation on the angle point thereof in box portion 7, this such that in the rest position of this member 21 an arm part 22 thereof is positioned in the path of movement of the enclosure 2 in channel 6.
- the other arm part 23 of knee lever 21 is provided wit a cutting member 24.
- Cutting device 25 comprises for this purpose a knife blade 27 received in a chamber 26. Connecting onto chamber 26 as finger protection 28 is a standing edge 29 of a cover 30. The knife blade 27 is thus inaccessible for fingers (particularly important with respect to children) , while the enclosure 2 can still reach the knife blade 27 for performing of the cutting operation.
- Chamber 26 is accessible via cover 30 which is fastene thereon using screws.
- the cutting means 20 are also accessible via a detachable cover 31 for replacement or servicing.
- the feed of a strip of paper tape 17 along the through-feed means 19 takes place via a passage 41 located between the cavity 8 and the channel 6.
- This passage 41 is wholly closed off at the sides by the side surfaces 4 and 5, which prevents undesired shifting of paper tape 17 in sideways direction.
- Passage 41 must have the narrowest possible through-feed opening for paper tape 17, as otherwise when the enclosure 2 is fed through the channel 6 at great speed the reel 13 with adhesive tape 12 will, as a result of the therein occurring jerking movements, continue to rotate through a certain angle, whereby the unwound strip of adhesive tape 12 is pulled back again to the reel 13. This also results in a long strip of paper tape 17 also being pulled back along the blades 11 to the reel 13.
- the box part 8 is provided with blocking means 42 which protrude into channel 6 and which co-act with blades 11 as a ratchet mechanism in order to prevent the return rotation movement of rotor 10.
- blocking means 42 which protrude into channel 6 and which co-act with blades 11 as a ratchet mechanism in order to prevent the return rotation movement of rotor 10.
- a possible embodiment of said blocking means 42 is obtained by embodying these means as a strip-like element 43 and manufacturing them from resilient material, wherein this element takes the form of an arcuate profile at the end 39 protruding into the channel 6.
- This outer end has to co-act with the blades 11 of rotor 10, this such that rotor 10 is on the one hand not impeded in its rotation movement during feed of an enclosure 2 through channel 6 but is on the other hand blocked when rotor 10 wants to begin a return rotation movement.
- the other end 46 of strip-like element 43 is anchored in a groove-like clamping point 48.
- the folding cover 35 as seen in the plane of movement thereof, widens on the side of the channel 6 and forms with the underside running out towards the channel 6 the upper wall 49 of the passage 41.
- the bottom wall 36 of passage 41 is a fixed bridge piece between both side surfaces 4 and 5 and co-acts form-fittingly with the upper wall 49 forming part of the folding cover 35 when the folding cover is in the folded down position, as shown in this figure.
- the part of the device for forming a closing strip shown in fig. 6 is identical to that in fig. 5, wherein however in fig. 6 the folding cover 35 is pivoted upward through a certain angle.
- FIG. 7 A very practical embodiment of a device for applying a closing strip for domestic use is depicted in fig. 7.
- a slide-away protective cover 51 is arranged for this purpose in side surface 4 of box unit 7.
- the reel 13 with adhesive tape 12 can be placed in position and the adhesive tape 12 guided toward the blades 11.
- the protective cover 51 can then be re-arranged in its position.
- protective cover 51 can be pressed from the side onto side surface 4, recommended in this embodiment is a protective cover 51 embodied as a slide cover for sliding of the protective cover into the opening.
- the slide profile parts in protective cover 51 and the side surface 4 herein co-act form-fittingly.
- the protective cover 51 further has a strip 52 standing at right angles to the slide cover, which prevents the reel 13 from being able to come out of the box unit 7.
- This embodiment likewise has several passage openings in base plate 3 of the device enabling a screw fastening of the device on the wall.
- FIG. 8 An enhanced embodiment of the cutting means 20 with spring mechanism 33 is shown in fig. 8.
- the member 21 embodied as knee lever and rotatable on an angle point is provided successively on the outer peripheral surface, running from the arm part 22 protruding into the channel 6 in the direction of cutting member 24, with bifurcated locking means 37 and with a bend 47 profiled as a bulge.
- the fixing position of the spring mechanism 33 fixedly situated in housing 1 is also embodied here as bifurcated locking means 50.
- the spring mechanism embodied as a spiral spring is replaced by a spring mechanism 40 manufactured from plastic.
- the spring mechanism made of plastic is embodied here as a plastic spring strip 44 with two bends 38 and 39 running in opposing directions, wherein the transition part 53 of both bends 38 and 39 lies against the bend part 47 of member 21 with the bulge profile.
- the extremities 54 and 55 of spring strip 44 take a thickened form and are received therewith in the associated locking means 37 and 50.
- Both bends 38 and 39 are preferably of equal size so as to be able to absorb the spring tension in equal measure.
- closing cover 35 acting as closing means not as a folding cover but as slide cover. This latter can then be pushed sideways away from the channel 6, wherein the drum-shaped space 34 becomes freely accessible.
- Slide profile parts in slide cover 35 and box part 8 herein co-act form-fittingly.
- FIG. 9 is an embodiment of a device for applying a closing strip which satisfies the above stated requirements.
- This device is provided in the side surface 4 at the position of the roll 12 with a cover plate or plate cover 57 embodied for sliding out in upward direction.
- cover plate 57 this is also provided with a suitable portion of the peripheral edge surface (upper edge) , which is then fixed at right angles to the surface part of cover plate 57 fitting into the side surface 4.
- Cover plate 57 can for instance be embodied with a form-fittingly embodied slide-in mechanism and/or be arranged in position with a snap connection. In the case the slide-in mechanism is used the slide profile parts in cover plate 57 and the side surface 4 co-act form-fittingly.
- cover plate as an element which can be moved aside on a pivot shaft.
