  • the present invention relates in general to folding machines for soft goods, and more particularly it relates to a folding machine capable of performing a plurality of folding operations on soft textile goods and which is provided with a plurality of folding members which are arranged one after the other and operating in a predetermined operating cycle.
  • folding apparatus For the folding of underwear there are several folding apparatus known in which the article undergoing the folding operation remains stationary during the entire folding operation. This means that the machine performs only pure folding movements. In such machines, the article undergoing the folding is placed on a supporting surface and by folding over the two end or front edges and the two longitudinal side edges, it is brought to its final folded shape.
  • folding apparatus are provided with so-called folding flaps, each of which performs a pivoting movement about an axis lying parallel with respect to the fold which is to be performed.
  • the second folding flap which becomes operative after the first folding flap, can start its operating movement only when the first folding flap has been returned into its inoperative or initial position.
  • the operating cycle of such folding apparatus is, consequently, relatively large and, it is practically represented by the sum of the individual operating times of the individual folding steps.
  • German DAS After recognizing the above disadvantages, there became proposed a folding machine capable of performing multi-folding steps on soft folded articles which has a plurality of longitudinal and transverse folding pushers or members and which are operated in a predetermined operating cycle and cooperating with each other.
  • such proposed apparatus for soft goods comprises a pair of upper folding plate members operated in a direction opposite to each other in a horizontal plane and a plane transverse to the horizontal plane, a pair of transverse folding arms arranged below the pair of upper plate members operated in a direction opposite to each other, a pair of longitudinal side folding arms arranged at a different plane with respect to each other between the folding plate members and the transverse folding arms and being operated in a direction opposite to each other, a transverse folding plate arranged in the region lying between the transverse folding arms and being operated to be insertable into the space between the pair of transverse folding arms pressing the transverse folding plates are pressed onto a bearing surface, the longitudinal side folding arms, the upper folding plate members are arranged to form a first folding group while the transverse folding plates and said transverse folding arms are arranged for forming a second folding group.
  • an object of the present invention to provide a folding machine capable of performing a multi-folding operation which has a plurality of folding members arranged one after another and operated in a predetermined operation cycle, in which the article undergoing the folding operation will perform only pure folding movements, and in which the possibility is provided that the individual folding members can perform a folding operation simultaneously on articles which follow each other.
  • an auxiliary fold supporting plate which can be operated in a predetermined cycle into and out of an operating position.
  • the article under folding can be placed in its fully extended shape onto a stationary cover means arranged above the longitudinal fold performing member, which when the auxiliary fold supporting plate is in its operating position and lying under an opening in the cover means, can support the article.
  • auxiliary fold supporting plate becomes, at the end of the folding process performed by the first folding group, shortly returned into its inoperative position so that the middle region of the prefolded article can be moved by a slight amount downward by the transverse folding plate of the second folding group which moves downwardly at that instant.
  • the second group of the folding members commences its folding process and the auxiliary fold supporting plate can be moved again into its operative position in order to receive the next-following article and, thereby, to make the insertion time and part of the operating time of the first group of thefolding members on the next-following article overlap or extend into the operating interval of the second group of folding members.

  • the folding apparatus according to the present invention itself includes a stand 4 on which a pair of longitudinal side folding arms 5 and 6 are guided for movement transversely over each other and are displaced in height with respect to each other.
  • the movement of the longitudinal side folding arms 5 and 6 is effected by means of a pneumatic cylinder arrangement which is not illustrated in the drawing to avoid a crowding of the essential parts of the invention.
  • cover means 7 which is illustrated by the dashed lines in FIG. 1 which serves as the bearing table or supporting table for the folding article 1 in its spread out state, that is, before folding.

  • a bearing surface 16 for the goods on which the foldingoperation has been completed which, in the illustrated embodiment, includes a plurality of closely arranged conveyor bands 17.
  • Such conveyor bands 17, as it can be seen in FIG. 2, are guided by a pair of guide rollers 18, 19 mounted in the stand 4, and their purpose is to bring the readily folded articles 1' into the region of a stacking station 20.
  • the a stacking station 20 is provided with a stacking arm 21 which brings the folded goods on the stack from below and up by means of carrying arms 22 which are pivotably joumalled on rods 23.
  • a shute 24 behind the guide roller 19.
  • both longitudinal side folding arms 5 and 6 are in their rest position under the cover means 7, while the oppositely lying front edges of both folding plate members 10 and 11 are displaced at a distance with respect to each other which corresponds to the largest length L of the good 1 to be folded.
  • Both folding plate members 10 and 11 the width of which correspond to the fold pa-v rameter E are in their initial position, that is, somewhat sideways of the two frontal sides 3 of the good 1 to be folded, and below the plane of the cover means 7.
  • the transverse folding plate 12 the width of which corresponds to the fold parameter E is in its initial posi- 5 tion and is below the longitudinal side folding arm 6.
  • the two transverse folding arms 13 and 14 which cooperate with the transverse folding plate 12 are in their initial position in which the distance between their frontal edges is somewhat larger than the transverse fold parameter E They are at a position under the level of the transverse folding plate 12.
  • the auxiliary fold supporting plate 15 will not under these conditions assume its inoperative position illustrated in FIG. 1 in which it is located underneath the longitudinal side folding member 5, but it is rather in its operating position in which it covers a surface area formed by the two transverse fold members 13, 14 and also by the folding parameters E and E From such initial position of the folding members, it follows that the article under folding 1, will lie on the cover means 7 with the regions of its longitudinal side 2.
  • the middle region of the article 1, the width of which substantially corresponds to the folding dimension E lies above the opening 7 of the cover means 7 and, as a result, it sags down by a slight amount. This region ofthe article 1 lies on the auxiliary fold supporting plate 15.
  • both folding plate members and 11 of the upper folding plate 9 perform a movement toward each other and also downwardly thereafter. They are moving through the recessed region 7 of the cover means 7, and at the end of their movement they come to rest on the auxiliary fold supporting plate 15.
