Patent Application

One method of making banners is to bond together two polymeric sheets of material using heat and pressure. The edges of the banner must then be hemmed to avoid fraying of the edges and provide support for the installation of grommets or rings. The grommets or rings are used to properly mount the banner in a location where it is visible and useful.
The present disclosure provides a banner hem sealing apparatus for use with impulse sealer and method of using the same. The apparatus is designed to reduce the misalignment problem caused when an impulse sealer is used to hem a banner. The apparatus is comprised of: a first member which comprises a tray and the means to mount to a second member; and the second member which comprises an opening, a fence, a backplate, and the means to mount to the first member.
The tray of the first member is designed to hold the banner during the hemming process. The tray may vary in length, width, and height to accommodate the expected banner requirements.
The means to mount the first member to the second member may be embodied in different ways. One embodiment is to use a wing nut and bolt on each side of the apparatus. The bolts are inserted into a holes existing on each side of the first and second members of the apparatus and secured with the wing nuts. Instead of a circular hole, an oblong oval may be used to allow different settings for mounting the first member. Alternately, a plurality of holes may exist to allow different settings for mounting the first member to the second member.
The opening of the second member is used to allow the impulse sealer to operate properly.
The fence is used to enable alignment of the banner during the hemming process. The fence is typically ½″ to 2″ high. The length of the fence matches or exceeds the length of the impulse sealer element.
The backplate is used to mount the apparatus to an impulse sealer.
One method of making banners is to bond together two polymeric sheets of material using heat and pressure. The edges of the banner must then be hemmed to avoid fraying of the edges and provide support for the installation of grommets or rings. The grommets or rings are used to properly mount the banner in a location where it is visible and useful.
Typically, the banner edges are hemmed in one of three ways. The first method is to sew the hem. This is labor intensive and requires a specialized sewing machine. The second method is to tape the hem. This is also labor intensive and can get messy if the tape is misapplied. The tape adhesive may also fail in both interior and exterior applications. The third method is to seal or weld the hem using a combination of heat and pressure. This may be accomplished with an impulse sealer. However, using an impulse sealer to hem a banner is labor intensive and prone to hem misalignment.
The present disclosure describes a banner hem sealing apparatus, hereafter referred to as the apparatus, designed to reduce the misalignment problem caused when an impulse sealer is used to hem a banner. One unexpected result is that the apparatus also reduces the labor cost of hemming a banner.
Another unexpected result is that the apparatus may be used to make pole pockets. A pole pocket is the opening that is required to mount a flag on a pole. Creating a pole pocket on a banner allows it to be used as a flag.
Another unexpected result is that the apparatus may be used to make a pocket sign. An embodiment of a pocket sign is a rectangular banner which is folded in half to make a creased top edge. The pocket sign is then hemmed on the two sides. A wire or some other mounting device is inserted in the bottom of the pocket sign. To use the pocket sign, the opposite end of the wire or mounting device is stuck into the ground.
The apparatus is comprised of: a first member which comprises a tray and the means to mount to a second member; and the second member which comprises an opening, a fence, a backplate, and the means to mount to the first member.
The tray of the first member is designed to hold the banner during the hemming process. The tray may vary in length, width, and height to accommodate the expected banner requirements.
The means to mount the first member to the second member may be embodied in different ways. One embodiment is to use a wing nut and bolt on each side of the apparatus. The bolts are inserted into a holes existing on each side of the first and second members of the apparatus and secured with the wing nuts. Instead of a circular hole, an oblong oval may be used to allow different settings for mounting the first member. Alternately, a plurality of holes may exist to allow different settings for mounting the first member to the second member.
The opening of the second member is used to allow the impulse sealer to operate properly.
The fence is used to enable alignment of the banner during the hemming process. The fence is typically ½″ to 2″ high. The length of the fence matches or exceeds the length of the impulse sealer element.
The backplate is used to mount the apparatus to an impulse sealer.
For the purposes of this disclosure, an impulse sealer comprises the means to apply heat and pressure to create a hem.
The method used to make a banner hem comprises: folding the banner along the side where the hem will be; placing the edge of the folded side adjacent to the fence; and activating the impulse sealer to apply pressure and heat to the folded side.
While the disclosure describes embodiments and various alternatives thereto, it should be apparent that the invention is not limited to such embodiments. Rather, many variations would be apparent to persons of skill in the art without departing from the scope and spirit of the invention.
