Definitions
- the present invention relates to a method of manufacturing a slider for affixing to the underside of a relatively heavy object that can be moved such as a piece of furniture (particularly a chair, an armchair) or the like, for facilitating the movement of said object by dragging on a surface such as a floor.
- sliding glides are already known which are distinguished from each other by their shape, the nature of their materials constituting on the one hand the base intended to be affixed to the furniture and on the other hand the sliding surface intended to be in contact with the ground.
- slider pads consisting of a base of a plastic material or an elastomer (eg rubber) coated with a PTFE layer (abbreviation polytetrafluroethylene) on the face intended to be in contact with the ground.
- a PTFE layer abbreviation polytetrafluroethylene
- the PTFE layer is obtained by injection molding.
- This fabric may be made of natural materials (wool, cellulose) and / or synthetic (for example plastic materials such as polypropylene, polyamide, polyethylene terephthalate or mixtures of these polymers).
- slider pads are generally in the form of felt rings. Their manufacture is easy, by simply cutting in a material in the form of a plate or a roll of a felt material. Unlike slider pads with a rigid plastic base, these felt sliders are not noisy. Indeed, the felt attenuates the noise. In addition, they avoid scratching the ground.
- a slider pad slightly different from the felt slider pads is to cover these felt pads with straight edges of a layer of PTFE.
- a layer of PTFE has the combined advantages of the felt base (ie less noisy than a base of plastic material) and a good sliding surface thanks to the PTFE coating layer which increases the sliding of the furniture on the floor compared to a slider pad only made of felt.
- this slider skate because of its straight edges, has the disadvantage of risking clinging to tile joints or any other roughness that may present a floor.
- the slider pads made of felt, and where appropriate the slider glides felt with a PTFE sliding surface are not fully satisfactory, because they may cling to the asperities that can present the soil.
- slider pads whose attachment means furniture is an adhesive
- the manufacturing processes slider pads can be complex and inexpensive to implement.
- the means for fixing the shoe to the furniture is a nail, it requires an additional step after cutting slider pads which is generally complex to perform.
- the present invention proposes to overcome these drawbacks detailed above that are known slider pads currently on the market. Indeed, the present invention provides a method of continuous manufacture of a slider which is economical and easy to implement. In addition, the gliding pad thus obtained by this method has the advantages of not being able to cling to the asperities of the ground (for example at tile joints), and this with a quality slip and without causing noise.
- the method of manufacturing a slider pad with rounded edges comprises the following steps.
- At least one felt element which has: a first face covered with an adhesive, said adhesive being coated with a protective layer and a second face opposite to the first face;
- a plurality of cutouts the shape of which is suitable for obtaining a plurality of slider pads which each have a first face covered with the adhesive coated with the layer, is made in the felt element. protective and a second face opposite to this first face;
- the second face of each of the slider pads obtained in the cutting step is heat-pressed so as to make said second face of each of the slider pads convex.
- the adhesive may be chosen from acrylic glues, rubber, silicone, polyurethane or any other equivalent adhesive known to those skilled in the art.
- the protective layer may be chosen from silicone papers and silicone films.
- Silicone films are plastic materials such as polypropylene, polyethylene or polyethylene terephthalate which have been coated with silicone.
- the protective layer is a silicone film made of polyethylene terephthalate, since it has the advantages of having good mechanical strength and temperature. In addition, it is transparent, which is generally preferred by users from an aesthetic point of view.
- the protective layer is removed to be able to glue on an object (for example a piece of furniture or the like) the first face of the slider which is provided with the adhesive.
- the second face of the felt element is coated with a layer of a low friction material, preferably about 0.04.
- This layer makes it possible to improve the sliding of the slider pad obtained according to the method of the invention.
- this layer is bonded to the second face of the felt element.
- this layer is made of a plastic material selected from the group consisting of polyethylene (preferably high molecular weight polyethylene), polypropylene, nylon, polytetrafluoroethylene (PTFE), polyoxymethylene and mixtures of those -this. Preferably, it is polytetrafluoroethylene (PTFE).
- This layer improving the sliding of the slider pad has a thickness which represents a very small part of the total thickness of the slider pad according to the invention. The thickness may be between 30 ⁇ and 1 mm, preferably between 50 ⁇ and 600 ⁇ .
- the slider obtained according to the method of the invention does not create noise problems when moving the object such as furniture, because it consists essentially of a felt material which is known for its absorbent properties. noise.
- the slider pad obtained according to the method of the invention is made of felt and has a first face covered with an adhesive which constitutes the attachment means to the heavy object that can be moved (for example a piece of furniture such as chair or armchair) and a second face opposite to the first face which is intended to be in contact with the surface on which the furniture is moved.
- this second face may be covered with a layer of a low friction material, preferably about 0.04, in order to improve sliding of the slider.
- the felt element can be in various forms among which can be mentioned:
- the roll preferably of a thickness of between 1 and 7 mm, preferably between 3 and 5 mm;
- the plate advantageously of a thickness of between 1 and 7 mm, preferably between 3 and 5 mm.
- the felt of which the slider pad is constituted can be chosen from the following materials:
- plastic in particular from the following polymers: polypropylene, polyamide, polyethylene terephthalate or mixtures of these polymers.
- the cuts are made appropriately according to the desired shape of the slider that is desired at the end of the process.
- they are washers with a diameter of about 10 to 50 mm.
- the hot pressing step is suitably carried out to round the edges of the second face of the slider pads, or in other words to make the second side of the slider pads convex.
- This step is advantageously carried out at a temperature of between 130.degree. 200 ° C, for example with a metal tooling of aluminum or any other material which has a thermal conductivity suitable for rounding the edges of the slider pad.
- the temperature may be adapted according to the felt used for the manufacture of slider pads. Of course, this adjustment of the pressing temperature is perfectly within the reach of the skilled person.
- the hot pressing temperature can then be more higher than for a felt slider.
- the temperature may be of the order of 200 ° C to 250 ° C; which will also have the advantage of reducing the duration of this hot pressing step. Temperature adjustment in this embodiment of the invention is also within the abilities of those skilled in the art.
- the hot pressing step is carried out at a temperature which may be between 130 ° C. and 250 ° C.
- the sliding pads have a second convex face prevents them from clinging to the tile joints or any other roughness of the floor when moving the object such as a piece of furniture. In other words, it improves the sliding of the slider pad, and this while limiting the forces applied to the felt during the passage of these asperities. Therefore, these rounded edges contribute to:
- edge of the gliding pads is often the part of these pads that tends to clog up the most by collecting dust. Rounding the edges of the gliding pads by hot pressing also has the advantage of limiting the accumulation of dust on their edge.
- the cutting and hot pressing steps are performed simultaneously in the same tool, for example in a tool having both cutting blades and concave surfaces made of a material having a suitable thermal conductivity (eg aluminum) for making cuts and rounding the edges of parts at high temperatures, ie up to temperatures of about 250 ° C.
- a suitable thermal conductivity eg aluminum
- total cuts are made, ie cut-outs throughout the thickness of the felt element.
- the felt, the adhesive and the protective layer are cut simultaneously so as to obtain sliding pads in the form of unitary pieces.
- so-called "half-flesh” cuts are made, ie cuts only in the thickness of the felt and the adhesive of the felt element. In other words, the protective layer is not cut.
- the method according to the invention further comprises a stripping step, so as to remove the excess material from the felt element which is, remembered, provided on its first side of adhesive. A plurality of slider pads are thus obtained which are fixed by means of the adhesive on the protective layer.
- the stripping step can be performed before or after the hot-pressing step.
- a step of guillotining of the protective layer is carried out so as to obtain a plurality of protective layer plates on which the gliding pads are placed, namely a limited number of gliding pads. , for example a dozen slider pads.
- the guillotining step is perfectly within the reach of the person skilled in the art. It is often performed according to commercial imperatives of presentation and storage of slider pads.
- the guillotine can be realized:
- the hot pressing step is carried out before the step during which the plurality of cuts is made.
- the method of manufacturing slider pads according to the invention is simple to implement and very economical.
- the method has the advantage of directly obtaining sliding pads arranged on protective layer plates that are ready to be shelved in the magazines, possibly after a final step of packaging. In other words, at the end of the process according to the invention, slip skids are obtained ready for marketing, without the need for additional steps (expensive and sometimes complex) of packaging this product.
