Definitions

  • the invention relates to a method of lath profiling used for making parquets and to a squaring machine which makes such a method for profiling laths.
  • suitable squaring machines make on one lateral side of the laths a male profile joint and on the opposite lateral side a female profile joint.
  • the joint profiles are connected one with each other and the floor surface is overlaid through a plurality of laths alongsided and connected one with each other joining the male element of each one in the female element of the adjacent lath.
  • the squaring machines used comprise a frame provided with a plurality of operating units, each one having a rotating tool with a profile suitable for making in the lath the desired profile.
  • the squaring machine is provided with a chain on which the working laths are head - tail aligned one after each other.
  • the chain advances continuously along the longitudinal direction of the frame and the laths are hold adherent through suitable pressure means generally made by an higher track.
  • the laths are worked in correspondence with the ribs by the operating units tools located two by two one opposed with another and operate at the same time on both ribs of the laths themselves.
  • the lath advancement chains are composed by a plurality of grids one pivoted after another in order to make a closed ring which is advanced along the longitudinal direction of the frame through gears, being at least one of them motorized, which engage the grids.
  • the chains are provided with slipping pads, which lean on sliding guide integral with the frame and internal to a protection case.
  • the case width is lower than the finished width of the lath which is easily manufactured in correspondence with the ribs of the shaped tools applied to the operating heads.
  • the parts of the lath to be manufactured project with respect to the case containing the chain and therefore they can be easily reached by the operating heads tools, which operate rotating on parallel planes or perpendicular with respect to the working surfaces.
  • the chains used are slipping chains of the known type, built by the same applicant of the present patent.
  • a disadvantage of the slipping chains is the limited speed of advance they permit, varying between 40 and 45 m/minute.
  • Squaring machines which have advancing speeds reaching also 60/80 m/minute using slipping chains.
  • the present invention is intended to overcome such disadvantages and limitations.
  • operating heads forming longitudinal engravings on both faces and mounted on slanting saddles suitable for advancing the tool slantingly to said lath, are present in the squaring machine.
  • the chain supporting the laths is a rolling chain and is provided with a plurality of supporting plates on which they rest the working laths.
  • Each plate has its width both lower than the case width enclosing the chain and than the distance between the longitudinal engravings on each lath.
  • the plate height is sufficient to define on each side a reentering area with respect to the case housing the chain, which is delimited on the bottom of the case itself, sideways from the plate side and higher up from the lower surface of the working lath.
  • Such a reentering area allows the entering of the rotating tool slanting to the lath lower surface, on which the longitudinal engravings have to be made.
  • the raising of the sliding plane of the laths with respect to the case plane housing the chain through a plate having a width lower with respect to the distance between the engravings to be made on the lath, together with the slanting position of the tools allows the manufacturing of the lath lower surface making on it longitudinal engravings, one distant from another of a lower quantity with respect to the case width housing the chain.
  • the squaring machine of the invention As we can see in fig. 1 the squaring machine of the invention, indicated as a whole with 1, realizing the method being also an aim of the invention, comprises a base 2 supporting a plurality of operating heads 3, 4, 5, 6, 7, located one after another.
  • Each couple of operating heads is formed by two opposite operating heads, each one placed on one side of the squaring machine according to the arrangement seen as a title of example in fig. 17, relative to the first couple of operating heads 3, comprising the left 3a and right 3b heads one opposite to another.
  • the operating heads manufacture the laths L, which are advanced along the longitudinal direction of the squaring machine in the sense indicated by the arrow 8 of fig. 1 and 2.
  • a plurality of laths is located one after another, leaning on a chain 9, which is winded as a ring between a back gear 10 and a shaped front slide 11, where the back gear 10 is rotated by a power group, indicated as a whole by 12.
  • the chain 9, as we can see in greater detail in fig. 17, is a rolling chain, being composed by plurality of grids 13 linked one with another and of the type per se known, each one having a transverse pin 14 supported on its ends by rolling bearings 15, 16 leaning on respective tracks 17, 18 belonging to the frame 2 of the squaring machine.
  • the chain 9 is housed on the case 19 belonging to the frame 2 of the squaring machine and each grid 13 of the chain 9 is provided with a supporting plate 20.
  • Each plate 20 has a datum plane 21 preferably made using a material with a high coefficient of friction, on which the lower surface L' of the working laths L rests.
  • a presser 22 holds the laths L adherent to the datum plane 21 and therefore also to the grid 13 of the chain.
  • the profiling method of the laths which are the aim of the invention comprises, with reference to figg. 2 to 16, the following operations:
  • the distance D between the engravings S', S'' is lower than the width 24 of the case 19, each engraving being obtained using a rotating tool 3', 3'', 4', 4'' belonging to one of the operating heads 3a, 3b, 4a, 4b and having the rotating plane 30', 30'', 40', 40'' slanting with respect to the plane defined by the horizontal plane face L', L'' of the lath L.
  • each supporting plate 20 has its width 22 lower than the width 24 of said case 19 and the sides 25 vertically protruding from the case itself in order to define laterally to each lath L an zone Z limited by the lath L, by the side 25 of said plates 20 and by said case 19, suitable for housing the tools 3', 3'' making said longitudinal engravings S', S'' on the faces L' of said laths L leaning on the datum planes 21 of said plates 20.
  • finishing tools 7', 7'' are finished through finishing tools 7', 7'', as we can see in figg. 2 and 13 to 15 obtaining finished profiles M', F'.
  • toot and manufacture profiles made on the lath sides could be of a different type from the description, according to the final product we want to obtain.
  • the plates put on the advance chain of the laths could be of a different form or dimensions according to the working laths, but these must have a width not higher than the distance between the engravings to be made on the lower face of the laths and on the case width.
