According to another preferred implementation, tablet can be folded at the longitudinal direction of described tablet twice.Preferably, the distance between the parallel fold line is a tablet in half of the width of horizontal direction at least.This folding arrangement is known as C-folding sometimes, and when tablet is placed with overlapping relation preferably but not necessarily carry out this folding.
Realize described interconnection by the adjacent end portion that overlaps tablet at least partly.Overlap at least 25% by the length that will launch tablet along its longitudinal direction, can make the tablet interconnection.Described coincidence can up to and comprise and launch 50% of tablet length along the longitudinal direction.This coincidence is constant, but also can change according to predetermined parameters.
According to the of the present invention first optional embodiment, the coincidence degree that forms between the folded adjacent material sheets can be constant.And in whole assembled web may, each tablet subsequently is placed on its transverse forward portion on the transverse rear of last tablet, perhaps alternatively, described transverse forward portion is arranged under the transverse rear of last tablet.This can realize by following means, is about to the continuous width of cloth and is cut into the sheet of the layout that joins end to end and makes the relative to each other displacement formation coincidence along the longitudinal direction of adjacent sheet.
According to first embodiment of the first optional embodiment, described registration is to launch tablet along 25% of the length of its longitudinal direction.Assembled web may preferably, and is but not necessarily folding at alternating direction, so assembled web may adopts the z font to form folded.In folded after folding, have tablet transverse line in two every a tablet.Can start folding step by following manner, promptly be placed close to and be parallel to the folded outside that obtains, perhaps by described front being placed on folded two centre positions between the outside and parallel relatively that obtain with two outsides by preceding widthwise edge with tablet.The folded width that obtains equals tablet substantially in half of the length of its longitudinal direction.
Alternatively, assembled web may folds at alternating direction, so every the folded whole length of three tablet extend throughs.Can start folding step by following manner, promptly by the preceding widthwise edge with tablet be placed near and be parallel to the folded outside that obtains, perhaps by described front being placed on folded two 1/4,1/2 or 3/4 distances between the outside and parallel relatively that obtain with two outsides.Like this, the folded width that obtains equals the length of tablet along its longitudinal direction substantially.
According to second embodiment of the first optional embodiment, described registration is to launch tablet along 33% of the length of its longitudinal direction.Assembled web may preferably but not necessarily, folds at alternating direction, then the described folded whole length of each tablet extend through 1/3rd.Can start folding step by following manner, promptly by the preceding widthwise edge with tablet be placed near and be parallel to the position of the folded outside that obtains, perhaps by described front being placed on folded two positions of half between the outside and parallel relatively that obtain with two outsides.The folded width that obtains equals tablet substantially along 2/3rds of the length of its longitudinal direction.
According to the 3rd embodiment of the first optional embodiment, described registration is a spreading materials along 50% of the length of its longitudinal direction.Assembled web may preferably, and is but not necessarily folding at alternating direction, so half of the folded whole length of each tablet extend through.Can start folding step by following manner, promptly by the preceding horizontal edge with tablet be placed near and be parallel to the position of the folded outside that obtains.The folded width that obtains equals tablet substantially along half of the length of its longitudinal direction.
According to the of the present invention second optional embodiment, the registration that forms between the folded adjacent material sheets can change.As in the first optional embodiment, each tablet subsequently is placed on its transverse forward portion on the transverse rear of last tablet in whole assembled web may, perhaps alternatively, described transverse forward portion is arranged under the transverse rear of last tablet.This can realize by following means, is about to the continuous width of cloth and is cut into the sheet that joins end to end and arrange, adjacent sheet relative to each other is shifted with the distance of variable increase or variable minimizing along the longitudinal direction forms variable coincidence.
According to folding preferably of tablet of the present invention, but not necessarily, arrange along vertical substantially direction.When discrete tablet when folded bottom is assigned with, described coincidence can keep constant from the top to the bottom.Yet according to parameter, such as folded size, surface texture, friction and/or physical sheet size, what need provides from bottom to top that it overlaps reduce continuously folded.Such as, when folded height reduces along with the taking-up of tablet, fold the weight that acts on the orlop tablet and also reduce.Therefore, extract the required power of tablet out and will reduce, just need coincidence still less.For this being made compensation, described coincidence can increase towards folded bottom.According to the characteristic of tablet, described coincidence can launch tablet along selecting in the 25-50% scope of the length of its longitudinal direction.
Similarly, when discrete tablet when folded top is assigned with, described coincidence can keep constant from the top to the bottom.Yet in some cases, need provide so folded, promptly according to parameter, as size, surface texture, friction and/or the physical sheet size of superimposition distributor, folded have a coincidence that increases continuously from the top to the bottom.Such as, when folded height takes place to reduce along with the taking-up of tablet, the distance between the dispense aperture at folded top and dispenser top place will increase.For this being made compensation, and be sent for the extraction that guarantees last tablet can cause tablet subsequently, described coincidence will increase towards the bottom of distributor.As mentioned above, according to the characteristic of tablet, described coincidence can launch tablet along selecting in the 25-50% scope of the length of its longitudinal direction.
Folding of tablet with preliminary dimension and variable coincidence can be arranged to adapt to the distributor with the dispense aperture that is positioned at dispenser top or bottom.Marked on folded even increase the direction that overlaps, same folds in the distributor that also can be used on two types.Only need the user to discern to have the maximum folded end that overlaps with this end away from dispense aperture.
Tablet has been placed the formation assembled web may with coincidence relation after, folded for assembled web may is formed as mentioned above, then carry out folding step.Folding assembled web may realizes in the precalculated position by fold line transversely for this.When described coincidence when being variable, select the position of transverse line to realize the folded width of being scheduled to.
According to second preferred implementation of the present invention, the coincidence that forms between the folded adjacent material sheets can be by arranging parallel stacked on top of each other formation of each tablet with two.Opposite with the first optional embodiment, in whole assembled web may, each alternate sheet of the described width of cloth is placed like this, even its transverse rear is arranged in the top of the transverse forward portion of tablet subsequently, and its transverse forward portion transverse rear top of tablet in front.This is by being cut into first material discharging sheet with the continuous width of cloth, and second material discharging sheet after placing cutting on described first material discharging sheet is realized then.Every material discharging sheet of each first and second rows is arranged end to end or is arranged with predetermined fixed or predetermined variable distance between the opposite ends of continuous tablet.
Described interconnection can realize by the partially overlapping at least of adjacent end portion that makes tablet.Described tablet can overlap 25% coincidence that realizes interconnecting between 25% to 50% along the length of its longitudinal direction at least by launching tablet, need be before or after the set of first and second material discharging sheets, make that each tablet separates in every material discharging sheet.Described coincidence can up to and comprise and launch tablet along 50% of the length of its longitudinal direction.Before above first material discharging sheet after 50% coincidence only need second material discharging sheet after will cutting be placed on cutting, second material discharging sheet after the calibration cutting along the longitudinal direction.Described coincidence can be constant, but also can change according to predetermined parameters.
First and second material discharging sheets can be piled up each other and put, and their sides are separately overlapped in perpendicular, promptly have 100% lateral registration.Described lateral registration can be selected in 30% to 100% scope of the transverse width of tablet.
According to first embodiment of second preferred implementation, described overlap ratio is to launch tablet along 50% of the length of its longitudinal direction.Described lateral registration can be 100% of cross-web direction width in this example.
Partly overlapping first and second material discharging sheets are folding at least along the longitudinal direction once, to form assembled web may, the corresponding assign direction that forms folded tablet of wherein said longitudinal direction.Longitudinal folding line like this is preferred, but not necessarily arranges, thereby described tablet is folded half.Then, fold assembled web may in the precalculated position to form the folded of described tablet along fold line at horizontal direction.
According to second embodiment of second preferred implementation, registration is to launch tablet along 50% of the length of its longitudinal direction.In this embodiment lateral registration be tablet transverse width 50%.
Preferably, partly overlapping tablet can fold twice along the longitudinal direction of described tablet.Distance between the parallel fold line can for each tablet along the width of horizontal direction at least half.Assembled web may can be by the outside of material discharging sheet under the folded inward, non-coincidence limit, and covers described coincidence part fully and assign to realize.Then, the outside of last material discharging sheet, non-coincidence limit folded inward also cover first folded edge and described coincidence fully.Alternatively, by the outside of material discharging sheet under upwards and inwardly folding simultaneously, and the inwardly folding downwards upward outside of material discharging sheet, can obtain assembled web may.The assembled web may that this folding layout obtains have continuous part overlapping many to basic V-arrangement, relatively and the tablet that interweaves.
