Definitions
- the invention relates to a method for perforating individual blanks a flat material from the group leather, synthetic leather, foams, Paper, filter paper, cardboard and foils through at least one needle group with perforation needles, the cuts by an endless conveyor in the effective range of the at least one needle group guided and by at least one hold-down device from the perforation needles subtracted from.
- Perforation processes are used to make flat material either permeable to air and steam, i.e. breathable, make, or e.g. Filter papers a to give certain filter characteristics.
- the main areas of application are Cover materials for vehicle seats, parts for shoes, gloves, clothing and filter papers.
- the average Needle and perforation density per unit area is therefore low and not sufficient for many cases.
- the known device is of irregularly sized blanks neither intended nor suitable because it cannot be prevented can that the needles edge portions of the blanks between the steel strips pull out upwards, causing the device to lock can.
- the invention is therefore based on the object of a perforation method specify with which also finite and irregular or non-uniform Sections of the material with even distribution of the perforation holes and high hole density can be perforated per unit area can without blocking the perforation process.
- the object is achieved in that the blanks through a moving with the conveyor and for the Perforation needles permeable hold-down belt on the conveyor being held.
- Such a method can be particularly advantageous for leather and cuts be used because this material comes from natural Reasons only in finite sizes.
- the method can be stationary, e.g. B. in a kind of punch, quasi-continuously or with gradual transverse transport, or be carried out continuously.
- the hold-down band synchronized with the cuts through the effective area or nip of the at least one needle roller is guided.
- Such hold-down strap - of limited length - can be of one Supply roll pulled off, tensioned through the nip between the at least one needle roller and that on the conveyor transported blanks and then for renewed and especially multiple uses again on a take-up roll be wound up.
- the hold-down strap as a consumable use and glue it to the blanks, for example to make thin leather more resistant and then the composite is broken down into individual blanks again.
- the hold-down belt is an endless belt is executed and several times with the transport speed of the Blanks through the effective range of the at least one needle roller, i.e. is passed through the nip.
- Textile tapes in particular, can be used as material for such hold-down tapes
- Fabric tapes that are used have a sufficient lifespan compared to the perforation needles.
- the invention also relates to a device for perforating flat material from the group leather, synthetic leather, foams and foils with a conveyor for the flat material, with at least one needle group with perforation needles and with at least one hold-down device is arranged between the conveyor and the needle group and through which individual cuts can be removed from the perforation needles.
- such a device is in accordance with the invention designed so that the hold-down device is designed as a hold-down strap is in sync with the blanks through a nip between the at least one needle roller and the conveyor can be passed through.
- Such a device is also suitable as a universal device for the Perforating continuous material with high and even hole density, conversely, prior art devices are not for the perforation of irregular or irregular cuts own. It is with the subject matter of the invention by a corresponding Number of perforation needles without further hole densities with a single one Needle roller to reach up to 50 holes per square centimeter.
- the at least one group of needles consists of one needle roller each and if the hold-down belt is synchronous with the blanks through a nip between the at least a needle roller and the lying on the conveyor Can be cut through, especially if the hold-down tape is designed as an endless belt.
- the action of the hold-down strap is particularly advantageous if one guide roller in front of the first and one behind the last needle roller is arranged, by means of which the hold-down band can be held on the blanks is. This means that the wrap angle of the needle rollers kept as small as possible and the hold-down strap protected.
- FIGS. 1 and 2 Two embodiments of the subject matter of the invention are as follows explained in more detail with reference to FIGS. 1 and 2:
- a machine frame 1 is shown on which there is a conveyor 2 is located, which is designed as an endless conveyor belt 3. This is guided over two deflection rollers 4 and 5 and three support rollers 6 and consists of a tensile material, of which at least the outer Surface is soft and made of foam, a fleece or felt.
- the pedestals, drives and clamping devices are not shown for the sake of simplicity.
- needle roller 7 There is one needle group in each case axially parallel over the support rollers 6 Shape of a needle roller 7.
- the number of needle rollers is variable and aligned according to the required degree of perforation density, which at three Needle rollers behind the last needle roller 7, for example 150 holes per Can be square centimeters.
- the support rollers 6 and the needle rollers 7 each form one between them Roll nip 8, through - seen in order from the bottom up -
- the conveyor belt 3, the blanks 9 and a hold-down in the form a finite hold-down band 10 are passed through.
- This Hold-down belt 10 comes from a supply roll 11 and is on a Take-up roll 12 rewound, both in a support frame 13 are stored.
- the drive and braking (neither shown) will Hold-down belt 10 held around the deflection rollers 14 under tension.
- the hold-down belt 10 by guide rollers 15 and 16 downwards and horizontally stretched on the blanks 9 held, with the perforation needles also the hold-down tape penetrate.
- the blanks 9 are at the left end of the conveyor 2 placed and fall in a perforated state in a receptacle 17th
- FIG. 2 in which the same reference numerals are used, differs differs from FIG. 1 in that an endless hold-down belt 10a is used is by the horizontal displacement of the right guide roller 14th is held tensioned by a tensioning device 18, which by a Double arrow is indicated.
- the thickness ratios and the needle lengths are exaggerated.
