FR2516904A1 - Ribbon unwinding equipment for shop counter - has parting-off blade working in retracting sheath - Google Patents

Abstract

The unwinding equipment for ribbon or strip material is for mounting on a counter etc., and gives a clean cut. The ribbon etc. is parted off by a blade (10) e.g. a razor blade, working in a retracting protective sheath. The blade can be inclined to the plane of the ribbon, and the sheath can be held in the upper rest position by a spring, being moVed by pressure free of the blade to allow a cut to be made. The design avoids the use of a serrated cutting edge and consequent serration of the ribbon end, also the risk of injury to the fingers. The sheath can be made of nickel or chrome covered iron, steel or aluminium.

Description

The present invention relates to counter reels allowing the use and cutting of all varieties of adhesive tapes.

In known devices of this kind, the part carrying out the cutting of the ru ban is serrated, which causes an end of the ribbon, after cutting, itself serrated, therefore unsightly when its use is of commercial utility. -Moreover, it is easy to injure yourself on the teeth of the dispenser.

The clean cut dispenser according to the invention avoids this drawback and allows the use of adhesive tape printed on a self-adhesive label and cuts it frankly safely. The description which follows as well as the appended diagrams and drawings will allow a good understanding of embodiments of the invention.

The device according to the invention consists of a slicer shown assembled in FIG. 1. This slicer consists of two plates. A female plate shown in Fig 2, and a male plate shown in Figure 3.

The female plate has in its upper part 1, two holes. The male plate, in its upper part 2, has two pins, intended to receive: a blade 10, like a razor blade, preferably mounted with an inclination; The two holes of the female plate 1. The female plate coming to be housed and receive the two nipples from the male plate 2.

According to a first variant, the width of the slicer may be less or greater. According to a second variant, the height of the trencher can be lower or higher.

The lower part of the male and female plates consist of a housing 3 and 4 intended to receive a return spring 5. This housing with the same surface area on the two plates comprises in its middle a rod 6 intended to prevent the spring from being bent in front or behind forcing him to stay in line with his accommodation.

According to a first variant, it is possible to make a larger number of housings receiving the appropriate number of springs of smaller or larger sizes. The feet of Figures 2 and 3 are perforated to be fixed together on the base of the reel. The slicer is housed in the sheath to protect the blade upwards, it even held down by the spring. This piece receives the adhesive tape. The device according to the invention is composed of a sheath. The scabbard is made up of two plates of identical dimensions to the slicer plus a necessary width allowing the scabbard to slide easily on the slicer, but avoiding that there is play, its width is identical to the slightly slicer March slicer allowing the sheath to slide but avoiding the play. The rear part of the sheath Fig 4 is surmounted by a lip 7 slightly inclined towards the rear making it possible to receive the adhesive tape to miter that it does not come off the sheath. The front part of the scabbard
ig 5 does not have this lip. According to a first variant, the sheath can have a greater or lesser width. According to a second variant, the height of the sleeve may be lower. According to a third variant, the front part of the sheath fig 5 can receive a lip slightly inclined towards the front. The lower part of the sheath at its center is cut in the shape of an "M" 8 intended to receive the upper part of the spring 5. The spring coming to be housed only on the rear part of the M. The central tongue 9 of the N being slightly twisted to prevent the sheath from being released upwards. According to a first variant, the spring can be attached to the sheath on the front part of the M. According to a second variant, the spring can be fixed to the sheath on both. "M" sets.

According to a third variant the sheath in its lower part can receive several "M" intended to receive several springs.

The present invention has been made of iron covered with nickel plating and chromium plating. It can be made of steel, aluminum, and all metals allowing the machining of these parts. According to a second variant, the trencher and the sheath can be made of plastic allowing long-term use and having the qualities of solidity required.

 The device according to the invention makes it possible, by taking the adhesive tape and pulling a desired length of tape, by applying the adhesive tape and by pulling a desired tape tape, by placing the adhesive tape on the trencher at the appropriate place. (between two prints for example) and activating with a dry gesture down, to cut in a clean way the adhesive tape.

This clean cut dispenser. allows to cut the adhesive tape printed in labels, thus allowing to realize important savings. The device according to the invention allows, thanks to the blade 10, the clean cut of the adhesive tape while avoiding having the zig-iag of the teeth on the tape. The cutting system is associated with a sheath intended to protect the user from a poor gesture which could injure him.

Claims (3)

1. Countertop dispenser with clean cut characterized in that the cutting member is a blade 10, like a razor blade or the like associated with a retractable protective sheath. 2. Clean-cut countertop dispenser according to claim 1, characterized in that the blade wire has an angle to the plane of the clean-cut tape. 3. Countertop dispenser with clean cut according to the preceding claim characterized in that the sheath is normally maintained at rest in the high position by an elastic device and which allows the blade to be released to make the cut when pressure is exerted on the scabbard.
