Definitions

• the invention relates to the technical sector of wipers with automatic or semi-automatic cutting allowing the distribution of strips of materials to a given format or a selected format. These wipers find many uses for hand towels, toilet papers and others.
• FIG. 1 a dispensing apparatus of this type, defined in its generality.
• This apparatus comprises in a housing (1) a drum (2) including a cutting mechanism (3) of a web of material from a reel of material (4).
• This coil is either suspended from the carrier flange (5) established from the housing of the apparatus in a plane perpendicular to the bottom wall, or said coil of material bears on the drum itself.
• the drum has ends forming fingers overflow to bear against and centering on the receiving flange of the housing.
• the drum has along its length and on the peripheral periphery a gripping zone for fastening the strip of material to facilitate its unwinding.
• a pressure roller (6) bears on the drum.
• the space between them allows the passage of the strip of material.
• the drum has intermediate disc flanges, parallel, with a notch passage for the blade holder. This has been described in French Patent No. 2701016.
• French Patent No. 2701016 Depending on the quality of the wiping material generally made of cellulose wadding and its thickness varies according to the markets, European and American for example, it must ensure a retention of paper in the best conditions.
• the Applicant has proposed to arrange the drum with means that ensure the retention of the material web, either with self-gripping strips and therefore rough, or with the help of sleeves elastomeric material disposed along drum on all or part of its surface with the exception of the zone of passage of the cutting blade.
• the latter has also provided to arrange the drum with a plurality of parallel discs disposed in the longitudinal axis of the drum on which bears the band of material to be cut (French Patent No. 2701016).
• the Applicant is therefore interested in finding a satisfactory solution to maintain the use of elastomeric material sleeves, while maintaining the adhesion properties inherent to the nature of the elastomeric material over time.
• the solution provided by the invention meets this requirement in a simple and practical way, by maintaining the elasticity properties of the sleeves on the drum and retaining the adhesion properties of the wiping materials.
• the solution provided by the invention is simple, easy to implement and does not require a transformation of the dispenser wiper material that could generate significant mold costs and other investments of this type.
• the wiper material dispenser drum of the type comprising a longitudinal central core corresponding to the length of the drum and protruding at its ends to be positioned relative to the receiving flanges of the housing of the wiper. apparatus, said drum being arranged with an end disc having an opening for the passage of the blade holder, and opposite another notched end disc with offset a receiving profile support from the other end of the door -lame, and between the end discs of the drum, it is arranged with a plurality of intermediate discs arranged parallel and spaced from each other in a predetermined pitch, said intermediate discs and the end disc being arranged with a notch defining the housing area of the cutting device to allow its articulation and pivoting, said drum re having a sleeve of elastomeric material, is remarkable in that the drum receives one or more sleeves of elastomeric material which are tensioned around the disc parts constituting said drum, and in that this or these sleeves in the initial state of no solicitation have
• FIG. 1 is a front view illustrating a dispensing apparatus according to the prior art.
• FIG. 1 is a perspective view of the drum according to the invention.
• FIG. 3 is a view illustrating the configuration of the drum in exploded view before assembly, with a first embodiment by means of tensioning the sleeve or sleeves, the cutting device is not illustrated.
• FIG. 4 is a partial perspective view of the drum after assembly.
• FIG. 5 is a profile view of the drum.
• FIG. 6 is an alternative view of the attachment mode of the tensioning means.
• the drum for the wipe material dispenser is shown as a whole by (10). It has a central longitudinal core (10a) corresponding to the length of the drum and protruding at its ends (10b) to be positioned relative to the receiving flanges of the housing of the apparatus.
• This drum has in known manner an end disc (10c) having an opening (1Od) for the passage of the blade holder, and opposite another end disc (10e) notched with offset a support (1Of) Receiver profile from the other end of the blade holder. Between the end discs (10c-10e) of the drum, it is arranged with a plurality of intermediate discs (10g) arranged parallel and spaced from each other in a predetermined pitch.
• the drum is arranged to receive one or more sleeves (11) of elastomeric material which are tensioned around the disc parts constituting said drum.
• This or these sleeves in the initial non-stressing state have a diameter substantially greater than the diameter of the drum by having a certain elasticity of deformation.
• the intermediate discs (10g) and the end disc (10e) of the drum are thus arranged with an indentation (10h) of square configuration, the set of notches aligned as shown in FIG. 3 for example defining the housing area (12) cutting device by allowing its articulation and pivoting blade output in a known manner, and also the positioning of a means (13) for tensioning the sleeves or sleeves for the clapboard and hold at the bottom of the different notches .
• the elastomer sleeve is made in one or two parts positioned on the entire drum if it is not arranged with the transmission belt, or on two half parts of the length of the drum as shown in the figures of the drawings in the presence of the transmission belt.
• the means (13) for tensioning the sleeve part (s) is intended to rest on the visible upper part thereof or for sandwiching it against the bottom of the sleeve.
• notch (1Oh) This lowering thus causes the elastic deformation of the sleeve part or parts which surround the upper edges of the intermediate discs and of an end disc of the drum, by causing the formation of folds or corrugations between the consecutive intermediate discs, to ensure better holding of the material with the presence of a pressure roller.
• the tensioning means (13) is thus in the form of a horizontal bar (13a) for each sleeve or sleeve parts, this flat bar inserting itself into the notches of the aforementioned disk.
• This bar is attached to the drum according to two possibilities given by way of example and shown in the drawings.
• the bar (13a) has at the end end-shaped tabs (13b) in the form of hooks (13c) which adapt by being fixed on the complementary profile of the central core of the drum. .
• the core is thus arranged for example with retaining notches that allow somehow the clipping of the bar. This acts as a mounting bracket and can be easily dismounted when needed.
• the bar (13a) is made by connecting screws (14) which penetrate into the bottom thickness of the walls of the intermediate flanges.
• the fixing of the tensioning means (13) of the sleeves makes it possible to obtain a maximum tension with improved hardness in the contact of the web of the reel of material.
• the use of these means (13) further makes it possible to eliminate any static electricity with the contact of the strip of wadded paper material or the like.
• the number of stirrup-shaped bars for example is a function of the number of sleeves arranged on the drum according to the characteristics of the latter and its integration in wiping material dispensing devices.
