BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to a tape dispenser and relates particularly to a dispenser for carpet seaming tape used in the formation of seams between opposed edges of carpet pieces to be joined.
Carpet seams are commonly formed using a carpet seaming tape which is caused to adhere to the opposed edges of the carpet pieces to be joined. Several different types of carpet seaming tape are used, depending on the method adopted for causing the tape to adhere to the backing of the carpet pieces. One form of tape comprises a backing material, reinforcing material and a heat softenable adhesive, the adhesive being softened, or melted, by a heated iron passed along the top of the tape whereafter the edge portions of the carpet pieces to be joined are pressed onto the melted adhesive which is allowed to cure or harden by cooling.
In another form of tape, at least one electrically conducting heating element is incorporated in the tape and the adhesive is softened by electrically heating the heating element, such as is described in Australian Pat. No. 529,440.
It has been common practice up until now to locate carpet seaming tape beneath the edge portions of the carpet pieces to be joined by lifting those edge portions and physically placing the tape in position. The tape is often provided with a centre guideline to assist in locating the tape centrally beneath the seam to be formed. However, it is often difficult to accurately locate the tape in position, and the proper location and positioning of the tape can be time consuming.
It is therefore desirable to provide apparatus which will assist in locating a carpet seaming tape beneath the edge portions of the carpet pieces to be joined.
It is also desirable to provide tape dispensing apparatus which is of relatively simple construction and which can dispense tape from a roll thereof to the proper location beneath the edge portions of the carpet pieces.
SUMMARY OF THE INVENTION
According to one aspect of the present invention there is provided a carpet seaming tape dispenser comprising a support frame having a pair of downwardly and outwardly extending leg means, tape carrying means to support a roll of tape, handle means, carpet edge separating means disposed between said leg means, and guide means to guide tape from said roll to beneath separated edges of carpet to be joined.
In one particular form of the invention, the leg means comprise a pair of runners carried on legs extending downwardly from the suppport frame, the runners being adapted to rest on and be drawn along the carpet pieces to be joined on either side of the seam to be formed. If desired, wheels or rollers may be incorporated on the runners to assist in movement of the dispenser along the carpet edge portions.
In the preferred form of the invention, the carpet edge separating means comprises a pair of downwardly and outwardly extending guides which are adapted to engage beneath the edge portions of the carpet pieces so that, as the dispenser is moved along the line of the intended seam, the guides act to lift and separate the opposed carpet edges. The spacing between the guides is such that a seaming tape can pass between the separated edges to be located beneath those edges when the dispenser is moved along the seam. The tape carrying means may include an upstanding frame member having a transversely extending stub on which is located the roll of tape. Releasable holding means is preferably provided to support the roll of tape on the stub.
The handle means may comprise a handle pivoted to the support frame and movable to enable the dispenser to be drawn or pushed along the carpet from either end.
In order that the invention will be more readily understood, one embodiment thereof will now be described with reference to the accompanying drawings.
