DESCRIPTION:
BRIEF SUMMARY
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 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; 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, tape-like material further means are present for forming a tape piece in said closing strip during guiding thereover of the strip of adhesive tape guided via the rotor into the channel and the supplied strip of tape-like material, severing the formed closing strip from the closing strip tape.
Such a device is known from WO-A-88/08395. The device shown in this publication for applying a closing strip is provided with a cassette with a paper tape which is pushed into a suitable cavity in the side of the device. The drawback to the use of such a device with cassette lies in the costs associated with the use of such a cassette, in which are further arranged specially designed through-feed means with strip-like element to prevent undesired return of the paper tape to the cassette. After the paper roll has been used up, such a cassette does not allow of easy filling with paper tape by the user for re-use.
The invention has for its object to obviate this drawback. According to the invention 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.
The invention will now be further elucidated with reference to the accompanying figures, wherein:
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;
FIGS. 3 and 4 show two different positions of use of the device depicted in FIG. 2 during applying of a closing strip;
FIGS. 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; and
FIG. 9 shows a portion of a subsequent 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. For the sake of simplicity 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.
In preference the channel 6 is embodied over practically the whole length as a straight gap, which implies the advantage of an easier running guiding for enclosure 2.
The manner in which the closing strip is applied round the enclosure 2 will now be explained, also with reference to FIG. 2, wherein this figure shows a partly cut away and broken away front view of the device shown in FIG. 1.
