Definitions

  • the present invention relates to a sewing machine,for industrial use,which has been specifically designed for simultaneously performing a plurality of different seaming lines.
  • the document GB-A-2 188 951 relates to a seaming machine having two needle bars which are parallel to one another and perform on a same fabric piece two separated seamings, parallel and with the same type of stitch.
  • the machine disclosed in this document accordingly, is not adapted to carry out two consecutive seamings of different types as those which can be performed by Applicant's seaming machine disclosed in the new main claim.
  • the document DE-C-72258 discloses a seaming machine which is tilted on a side and enclosed in a casing in order to prevent possible lubricating materials from contacting the fabrics being seamed.
  • This is a machine including a single needle bar and which, accordingly, can not perform simultaneously different seaming operations Practically, the machine of this document operates as a conventional seaming machine in order to perform a single type of stitch at a time.
  • the document US-A-2 238 796 relates to a seaming machine which does not comprise any needle bar, since the needle of this machine is controlled by a lever and can perform exclusively a type of stitch.
  • the seaming machine of this document has been designed for facilitating the operation of seaming the edge portions of the fabrics, in particular a tubular fabric piece.
  • the machine disclosed in this patent can not perform simultaneously two types of seaming operations.
  • the documents DE-O-3 407 271 and CH-O-665229 relate substantially to the same machine.
  • the document CH-O-665229 is an improvement of the document DE-O-3407271.
  • These documents relate to a seaming machine which can simultaneously perform seaming operations on the opposite edges of a half-finished product. Practically there is herein disclosed a seaming machine having two symmetrical and opposite seaming heads which perform separately two equal seams on opposite flaps of a same fabric piece. The type of machine disclosed in these patents is not adapted to perform simultaneously two different types of seams.
  • the document FR-O-691277 relates to a seaming machine having two needle bars in a single block.
  • the positions of the control mechanisms and several control members are fixed Because of this reason, this machine can perform exclusively a type of work.
  • the control unit of the several control mechanism consists of a single shaft which drives a horizontal needle bar parallel to the shaft and a vertical needle bar perpendicular to the preceding one, operating the single provided crochet. Because of this reason, the seaming machine of this document can exclusively form a chain stitch with the horizontal needle, since this needle bar is parallel to the shaft driving it and since the crochet discloses during its stroke an ellipsoidal configuration perpendicular to the needle.
  • the vertical needle bar can form exclusively an ornamental stitch since in order to carry out a different type of stitch there are necessary two crochets.
  • the lower or bottom crochet is used for latching the yarn of the needle in the bottom portion of the seam
  • the top crochet is used for latching the yarn of the bottom crochet so as to bring it under the needle on the top portion of the seam.
  • the machine disclosed in this FR-A-691277 document has a single drive for the fabric, perpendicular to the vertical needle bar and is arranged bridging the vertical needles.
  • the horizontal needle bar does not include any drive for the fabric. None of these two needle bars is associated with a differential drive and accordingly the fabric, between the two needle bars, can not be spread or caused to shrink depending on the requirements.
  • the main object of the present invention is to overcome the above mentioned drawbacks, by providing a sewing machine,for industrial use,which is specifically designed and arranged to perform,in a single pass, two or more seaming lines, either of the like or different type.
  • Another object of the present invention is to provide such a sewing machine in which the fabric being sewn can also be fed or transported with different angles.
  • Another object of the present invention is to provide such a sewing machine in which the fabric flaps or portions to be sewn can be oriented in all of the working orienting directions,independently from the fact that said fabric portions are in a loose condition or in a partially assembled condition.
  • the sewing machine for industrial use comprises a supporting frame which has been specifically designed for supporting at least a main shaft 1 which is driven by an electric motor (not shown).
  • main shaft 1 there are keyed at least two pulleys,indicated respectively at 2 and 3,provided for transmitting a rotary movement to corresponding driven shafts 4 and 5 through corresponding belts 6 and 7.
  • Said driven shafts can also be driven by other driving sources,in a timed manner.
  • the driven shaft 4 supports a first cam member 8 which,through a connecting rod 9,a ball joint 10 and a swinging pivot sleeve 11,drives a lever 12 for controlling two or more needle bars 13.
  • These needle bars can be arranged in different planes,with different angles( with a single and timed driving assembly) and can support,by means of clamp members 14,corresponding or respective needles 15 which can be selectively operatively driven.
  • a second cam member 16 which,through a connecting rod 17,a ball joint 18,a sleeve 19 and a swinging pivot pin 20 drives a trimming knife 21 supported on a curved supporting arm and the blade of which is indicated at 22.
  • a third cam member 23 which,through a connecting rod 24, a ball joint 25 and a sleeve 26,drives a first swinging pivot pin 27 which in turn,through a lever,drives a second pivot pin 28.
  • pivot pins 29 and 30 which can rise gripper bearing sliders,respectively indicated at 31 and 32.
  • the gripper bearing slide 31 fixedly supports the gripper or clamp 33 which operates to feed the fabric to a needle or to the needles.
  • the slider 32 in turn,supports the gripper or clamp 34 for driving the fabric beyond the first needle assembly.
  • the gripper 33 can also be called “differential gripper” since it can carry out a different operating stroke from that of the gripper 34 which, in turn,can be called “ stitching gripper”.
  • This pivot pin drives rotatively the levers 40 and 41 which are respectively provided with driving pins 42 and 43,which,in operation,drives the respective gripper bearing sliders 31 and 32 so as to bring said sliders in contact with the fabric being sewn and cause said sliders to come back,in a lowered condition,under the control of the mentioned eccentric levers 29 and 30.
  • the disclosed sewing machine also comprises means for orienting the fabric portions to be sewn in all of the directions,independently from the fact that said portions are loose or assembled.
  • the timed operation of the mentioned grippers will provide a simultaneous and timed "transportation" of two or more seaming lines,owing to the different angles of the two or more seaming lines themselves.
  • This sleeve,as is shown,restrains a swinging pivot pin 48 thereon there is keyed a lever 49 bearing the lower hook member 50,which can perform a rotary movement.
  • a suitable protecting casing 60 is moreover provided,which advantageously also operates as an operating table.
