Description

The invention relates to an apparatus and a method for feeding

  labels for providing a label bearing an indication such as a size indication or a cleaning indication, in order to sew the label on a cloth in the form of a napkin,

  a suit or the like. The invention relates more particularly to

  particularly a label feeding apparatus and method for feeding the label so that an end sewn portion of the label is covered by the edge of the fabric and the marked portion

  be placed on the fabric internally at the edge.

  A conventional label feeding apparatus is provided in the following manner; that is, the label feed apparatus has a label retainer adapted to reciprocate between a label detent position and a label stitch position. The element of

  restraint arrives in the immobilization position of

  flip and pinch part of the label. The retaining member pinching the label moves to the seam position of the label and superimposes the leading end portion of the label on a predetermined sewing portion of the fabric. The superimposed extreme part is sewn by a sewing machine. An example of such an apparatus is described in the published and unexamined Japanese patent application,

N 63-281681.

  When the aforementioned fabric is wide, it is generally laid on a table placed in front of the sewing machine so that the fabric is smoothly advanced during a sewing operation. When the end of sewing is sewn on the edge of such an extended fabric so that the portion of the label bearing an indication is placed on the fabric internally at the edge, the conventional apparatus

  mentioned above for feeding labels comes to

  above said table. The label feeding apparatus thus placed, however, constitutes a major obstacle to the work to be performed on the fabric resting on the table, for example to the operation of spreading

the stuff on the table.

  The subject of the invention is an apparatus in which the label can be brought to be sewn on a fabric in an arrangement such as an extreme part.

  sewing of the label is superimposed on a predetermined edge

  finished sewing fabric and that part of the

  marked with an indication placed on the fabric

internally at the edge.

  Another object of the invention is an apparatus in which the label can be brought from outside the predetermined edge to be sewn when it is brought into the aforesaid arrangement. The apparatus capable of such a supply of labels may be placed in a position close to the aforementioned edge and away from a space above

  a table to support the fabric. The space

  above the table remains clear and this improves

  the efficiency of the work done on the fabric on the table.

  In the apparatus according to the invention, a part of the label in a label immobilization position is inserted into a holding element by a driving element. The holding member pinches the inserted portion of the tag. The holding member is moved to a seam position. During this movement of the holding member, the end portion of the label protruding from the holding member bears against the table or against the edge of the fabric and is folded into the

  opposite direction to that of the movement of the holding element.

  The end portion is then brought above the predetermined edge to be sewn from the fabric. In this situation, the part of the label pinched by the holding member is

  placed above the fabric internally at the edge.

  Another object of the invention is to provide an apparatus and method for feeding labels which can make it possible to bring a label so that the length of the end portion of the label protrudes from the element. Maintaining is fixedly established so as to be constant even when the length of the label to be provided changes. If the length of this end portion is constant, the extreme sewing portion of the label can be precisely placed on the edge of the fabric only by moving the holding member to a predetermined position, regardless of - the length of the label to be provided. This makes it possible to simplify the structure for moving the holding member to the seam position and simplifies the control of movement

of the holding element.

  Another subject of the invention is an apparatus and a method of supplying labels making it possible to feed a single label or a double label, the length of the portion of the label exceeding

  2C of the holding element being fixed and constant.

  in labels according to the invention, the apparatus 1 for feeding

  The label arrangement comprises a base frame 2, cutting means 3 mounted on the base frame 2, a label table 4 formed so that its upper surface establishes a label immobilization position in which a label is fed. , a label depressing means 5 provided under the label table 4, a holding member 6 provided above the label table 4 and label holding means for retaining a label

  part of the label on the table 4.

  The cutting means 3 have the function of cutting a long strip 10 labels and for other function to prepare the labels cut on the table

  4 labels. These cutting means 3 will now be described.

  A housing 11 of the cutting means 3 is mounted to move along a rail 12 placed on the base frame 2,

  in the direction indicated by an arrow in Figure 1.

  The housing 11 has, on a first side, an inlet 13 for the strip 10 and, on its opposite side, an outlet 14. The housing 11 encloses a support plate 15 for receiving the strip 10 between the inlet 13 and the 14 and the casing 11 further encloses two feed rollers 16. These feed rollers 16, which clamp the band 10 together, are rotated in the directions indicated by arrows in the figure by means of a drive motor, not shown. The strip 10 is pulled inward through the inlet 13 and pushed out through the outlet 14 by the rotation of the rollers 16 in advance. A knife 17 for cutting the web 10 is placed near the exit 14 in the housing 11. A reference sensor 18 for detecting cutting marks which are fixed on the web 10 to indicate the cutting positions is near the input I3 along the path of the strip 10. The latter consists of a number of elementary labels connected in series, to be

  shaped into labels separated by the section of the band.

  The aforementioned mark is fixed on each edge between adjacent elementary labels. As a result, the spacing between two adjacent markers on a strip 10 consisting of long elementary labels (a strip for producing long labels) is long, and it is short on a short strip 10 (a strip for the production of short labels). An example of the strip 10 is a textile tape. Another example is a smooth ribbon made of synthetic resin. The drive motor for the feed rollers 16 and the sensor 18 are connected to control means, not shown. The control means operates to rotate the drive motor and receives a signal from the sensor 18 when it detects the mark. The control means acts to stop the drive motor when the feed rollers have advanced the belt 10 just a distance for which the detected mark arrives at the position of the drive.

knife 17.

  A transfer means 21 is provided for moving the housing 11 along the rail 12. The transfer means 21 comprises two bearings 22 fixed to the base frame 2, an advance rod 23 supported by the bearings 22 in order to be rotatable, a handle 24 for rotating the feed rod 23 and a transfer member attached to the housing 11. The feed rod 23 is a threaded rod and is screwed into a threaded hole formed in the transfer member. When the rod 23 is rotated by the handle 24, the element 25 is moved.

  transfer along the feed rod 23 and, consequently,

  In the present embodiment, the label table 4 is connected to the housing 11 of the cutting means 3 and is adapted to be moved with the housing 11 by the transfer means. 21. A plurality of slots 27 are formed in the label table 4 and are designed to allow a driving member, described hereinafter, to pass through the label holding position. As shown in FIG. 1, each of the slots 27 is shaped to be elongate in the direction of movement of the table 4

  under the action of the transfer means 21.

  The aforesaid driving means comprises a driving element 31 and a reciprocating means 32 for subjecting the driving element 31 to reciprocating movement. The driving element 31, which has a plurality of driving teeth 33, is in the form of a comb. The width of each driving tooth 33 is such that each tooth can pass through a slot 27 of the table 4. The free end portion of each driving tooth 33 is wedge-shaped and the end is slightly rounded as shown in Figure 4A. However, the free end portion can be configured as shown in Fig. 4B. The reciprocating means 32 in this embodiment is an air cylinder 34 mounted on the base frame 2. The driving member 31 is attached to the upper end of a housing.

  piston rod 34a of the air cylinder 34.

  A rule or presetting means 36 is provided to limit the forward stroke of the driving member 31 to a predetermined value. This adjustment means 36 comprises an abutment element 37 made in one piece with the driving element 31 on its two sides, and a stop element 38 fixed to the table 4 with labels. The stop member 38 has a stop surface 39 on its side opposite to the stop member 37. The stop surface 39 forms an angle of 45 with the direction

  from the movement of the table 4 to labels.

  We will now describe the holding element 6.

  A body 41 of the holding member 6 is mounted on a well known support means 42 (only part of which is shown). The holding element 6 is reciprocated between a holding position A and a stitching position B as shown in FIG. 3. The body 41 has moving parts 41a, 41a designed to move towards or away from each other. one from the other. Each movable piece 41a comprises a holding piece 43 made of an elastic material. The top of each piece 43 of

  maintaining forms a holding portion 44. An anti-element

  sliding 44a (for example a piece of rubber), which

  can exert a great force of friction on the label.

  quette, is attached to the piece 44 of maintenance. The space between the holding portions 44, 44 forms a label receiving portion 45. The holding position A is determined to be at a location where the label receiving portion 45 is opposed to the driving member 31 so that the tag pushed back by the driving member can be received. in the label receiving portion 45. Label guides 46 are provided near the table 4 labels. The guides 46 are attached to the base frame 2, although this is not shown. The label guides 46 and the label table 4 are separated by a space in which the label may pass. A space 47 allowing the passage of the driving element 31 is

  left between the label guides 46 in a location o -

  the guides 46 are opposed to the driving element 31. If the top of the holding piece 43 is sufficiently close to the label table 4 when the holding member 6 is placed in the holding position A, it is possible to

  remove the 46 label guides.

  The aforementioned means 7 of retaining labels comprise an air cylinder 48 fixed on the housing 11 and a pressure bar 49 fixed on the upper end

  piston rod 48a of the air cylinder 48.

  Fig. 2 shows a label stitching means 51 as an example of means for receiving fed tags. The means 51 comprises a machine table 52, a fabric receiving table 53 made in one piece with the machine table 52, a machine head 54 provided above the table 52 and a transfer means 55. for transferring a fabric, having a sewing label, from the fabric receiving table 53 to the machine table 52. The transfer means 55 comprises a guide rail 56. A movable frame 57 is mounted on the guide rail 56 to move along it. An air cylinder 58 is mounted on the movable frame 57 and a stuffed bar 59 is attached to the lower end of the piston rod of the air cylinder 58. An anti-slip layer (eg a thin rubber band), exerting a high frictional force on the fabric, is attached to the lower surface of the fabric press bar 59. A feed mechanism 60 is connected to the movable frame 57. The feed mechanism 60 comprises a pulley 61 and a belt 62 (for example a toothed belt) passing over the pulley 61, and a connecting piece

  of the movable frame 57 is attached to the belt 62.

  The label feeding of the means 51 to sew labels using the label feeding apparatus 1 will now be described, and the seam of

  the label provided, in the seaming means 51

  quette. In the label stitching means 51, a fabric 64, on which the label is to be sewn, is placed to be spread on the table 53. An edge 64a of the fabric 64 constitutes a part on which a part Extreme sewing of the label is sewn. In this case, the label is provided by the power supply apparatus 1.

  labels as follows.

  First, the feeding of a relatively long double label will be described with reference to Figures 3, 5, 6A, 6B, 7A and 7B. To form labels of the type mentioned above, the strip 10 is used whose cutting marks are spaced a greater distance. The cutting means 3 and the table 4 labels are moved by the transfer means 21 so that the distance L1 between the knife 17 and the driving element 31 is equal to half the distance between the marks of cut above (half the length of an elementary label). In this case, the strip 10 is first moved by the rollers 16 in advance. Under the effect of this advance, the elementary label 10a corresponding to a label is output in front of the knife 17 and rests on the table 4 label as shown in Figures 6A and 7A. Then the rod 48a of the piston of the holding means 7 is

  animated with an extension movement and the elemen-

  shut is pressed down on the table 4 by the pressure bar 49. In this situation, the knife 17 goes into action. As a result, the elementary label resting on the table 4 is cut and becomes a label 65. In the tag 65, the leading end 65a and the trailing end 65b are end portions to be sewn and the intermediate portion 65c, including between the extreme parts, is a part bearing an indication. The strip is formed beforehand to include these parts. The holding means 7 is released. The rod 34a of the

  piston of the cylinder 34 is animated by a movement of exten-

  if we. The driving element 31 then bears on the intermediate portion of the label 65 resting on the table 4, as shown in FIGS. 6B and 7B, and pushes the intermediate portion into the receiving portion 45 of the element 6.

  maintaining through the space 47 guides 46 of labels

  quette. The driving member 31 continues to advance to a position in which the abutment member 37 bears against the stop surface 39. The depressed label 65

  is taken elastically by the parts 43, 43 of maintenance.

  Then the driving element 31 is withdrawn by the contrac-

  The holding member 6 is moved transversely to the seaming position B by the support means 42. As shown in FIG. 3, the locus of the movement of the holding element 6 is determined so that the locus of the movement of a part such as a portion 65d of the label, projecting downwards 6, for example the locus of the lower half of the portion 65d, can meet an obstacle constituted by an object close to the stitch position B, for example the table 53. Accordingly, when the element 6 holding is moved along the locus of its movement and approaching the stitching position B, the lower half

  the protruding portion 65d bears against the table 53.

  When the holding member 6 is moved, the projecting portion 65d is bent in the opposite direction to that of the movement of the holding member 6. When the holding member 6 reaches the seam position B, the end portions 65a and 65b to be sewn, constituting the end portions of the projecting portion 65d, are superimposed on the sewing edge 64a of the fabric 64. this situation, the indication portion 65c of the label 65 is obviously placed above the fabric, internally at the edge 64a. The aforementioned object, close to the seam position, may be the edge 64a of the fabric 64. In this case, the locus of the movement of the holding member 6 is determined so that the end portions 65a and 65b of the label 65 can bear against the edge 64a of the fabric 64 to be folded backwards as in

the case mentioned above.

  When the tag 65 is fed as mentioned above, the sewing means 51 operates as follows. The cloth press bar 59 is moved as indicated by arrows 66 in FIG. 2 under the action of the feed mechanism 60 and the cylinder 58 and presses down on the table 53 the fabric 64 and the 65. In this situation, the holding member 6 releases the label 65 and returns to the holding position A. Then the press bar 59 is moved by the feed mechanism 60 in the direction indicated by the arrow 67. Under the effect of this movement, the fabric 64, to which the label 65 is

  attached, is moved by sliding on the top surface--

  top of table 53, together with the press bar

  fabric 59, and reaches the upper surface of the table 52 of the machine. The fabric 64 is further moved by sliding on the table 52. During this movement, the head 54 of the machine sews the end part of the label 65 on the edge 64a of the fabric 64. When the When sewing is completed, the press bar 59 is raised by the cylinder 58 and the fabric 64 is released. The released fabric 64 is transported to be subjected to the next step. The aforementioned feeding and sewing operations of the label are repeated one after the other and a label is attached to each of the pieces of fabric. The operation will now be explained in the case where the label is replaced, for example by a label of shorter length. The band 10 used in this case is the band to which are attached closer cut marks. In the feeding apparatus 1, the distance between the knife 17 and the driving member 31 is decreased by means of the transfer means 21 to take a small value as shown at L1 'in FIG. 8A. In other words, this distance is adjusted to be equal to half the distance between adjacent cutting marks on the new band. The same operations are then performed as those carried out in the previous case. The situations that are then obtained are as shown in FIGS. 8A and 8B. These figures show situations corresponding to those of FIGS. 6A and 6B. In the case of the present operations, the advance of the driving element 31 is limited by the abutment entry of the abutment element 37 with the stop surface 39, while the advance stroke of

  element 31 is still small. The depth of introduction

  The penetration member 31 in the label receiving portion 45 is limited to a small value L 2 'as shown in FIG. 8B, in comparison with the depth L 2 as shown in FIG. 6B. The decrease in the insertion depth of the driving element 31 in the case of FIG. 8B, in comparison

  with the depth of FIG. 6B, is equal to the decrease

  (LI-Li ') the distance between the knife 17 and the driving element 31, since the stop surface 39 is formed to be inclined at an angle of 45. As a result, the length L3 of the label portion 65d protruding from the holding member 6 remains equal to the corresponding length in FIG. 6B. Therefore, when the holding member 6 is moved to the sewing position B, the end portion of the label 65 is superimposed on the edge of the fabric, similarly to the case of the long label, indicated above. The length L3 is called the length

necessary protruding.

  Simple labels are formed in the label feed apparatus 1 and can be fed to the seam means 51. The band used in this case is formed so that the rear end of the label cut at a mark (the end portion adjacent to the knife 17> can become the end part to

  sew and the other part is the part wearing one.

  indication. The single label is formed and advanced with the cutting means 3 and the label table 4 is moved by the transfer means 21 to the positions

  shown in FIGS. 10A, 10B and 11. In these positions,

  the distance from the lower end of the element 6maintien to the knife 17, passing through the space 47 between the label guides 46, is equal to the aforementioned length L3 (= L1-L2). When the table 4 is in the aforementioned position, the stop element 38 has already

  removed from above the stop element 37. As a result

  the driving element 31 can advance to the

highest position.

  The single label is formed and advanced by the respective means which operate according to the sequence of operations of FIG. 19. The difference from the case of the aforementioned double label (FIG. 5) is that the holding means 7 always retains the label during the entire cutting operation performed by the knife 17 and

  in advance of the driving element 31. -

  As shown in FIG. 10A, an elementary tag 0lob, corresponding to a tag, is first outputted to the table 4, similarly to the case of the double tag. The elementary label is then

  cut by the knife 17 to constitute a label 70.

  At this time, the trailing end portion, i.e., the end portion 70a of the label 70 on the table 4, is retained by the pressure bar 49 as shown in FIG. 20B. With the extreme sewing end thus retained, the driving element 31 advances to its uppermost position as shown in FIG. The other end portion of the label 70 then enters the receiving portion 45 of the holding member 6. The latter clamps the label 70. The end part to be sewn is then released and, furthermore, the driving element 31 is pulled outwards. This results in a situation in which the holding member 6 holds the tag 70. In this case, since the table 4 is in the aforementioned position, the length of the portion of the tag 70 protruding from the Element 6 of maintenance is equal to that existing in the case of the double label. This label 70 is advanced towards the seam means 51, similarly to the case of the double label.

  The operation of the food apparatus 1

  The labeling, for feeding a short single label, is quite similar to that of the previous case. In this case, the length of the portion of the label entering the receiving portion 45 of the holding member 6 is shorter than that of the previous case, as shown in FIG. 11. The length of the protruding portion of the element 6 of maintenance is however

  the same as in the case of the aforementioned long label.

  The driving element 31 of the label feeding apparatus 1 is in the form of a comb. Therefore, a wide label 65 'can be placed on the table 4 with labels and pushed by the element

  31 as shown in Figure 12.

  Figure 13 shows a second form of

  realization of the label feeding apparatus.

  The label feed apparatus shown in this figure differs from the label feed apparatus of the previous embodiment by reciprocating means 32e, depressing means 5e and holding means 7e. The reciprocating means 32e will be described first. A support frame 75 is mounted on the base frame 2e. The support frame 75 comprises two bearings 76, 76 and a threaded rod 77 is rotatably supported in these bearings. A motor 78 is mounted on the support frame 75 and the output shaft 79 of the motor is connected to the threaded rod 77 by a coupling 80. A movable member 82 is intended to effect a vertical movement along a portion 81 guide of the support frame 75. The driving element 31e is connected to this movable element 82. The latter is screwed onto the threaded rod 77. A motor is used for the engine 78 whose number of revolutions or the angle of rotation of the shaft 79 of output can be ordered. Such an engine

can be a stepper motor.

  In the reciprocating means 32e of this type, the driving distance of the driving member 31e can be controlled with greater precision by controlling the number of rotations or the rotation angle of the motor 78. In other words, the motor 78 functions as a presetting means to limit the race

  in advance of the element 31e de embedding.

  The securing means 7e is designed to retain the label by suction. For this purpose, a suction duct 83 is attached to the tab table 4e and one end of the duct, for example a suction element 84, is open in the upper surface of the table 4e near an exit 14e d a cutting means 3e. One end of a suction tube 85 is connected to the other end of the conduit 83 and a suction means 86 is

  connected to the other end of the tube 85.

  The double label or single label can be fed into this label supply apparatus by the same operation as in the aforementioned label supply apparatus. The double label can be fed in the following manner as well. Thus, the tab table 4e is positioned as shown in Figs. 15A-15C, in the same manner as in the case of feeding the single label in the previous embodiment. All the means operate according to the same sequence of operations as shown on the

  Figure 14, as in the case of feeding the label

  simple quette above. In the case of these operations, the element 31e of advance advances from the state of Figure A to the states of Figures 15B and 15C. The driving member 31e stops at a position in which the lengths of the portions of a tag 65e located on the right and left sides of the member 31e are equal to each other as shown in Fig. 15C. The advance of this type can be effected by controlling the number of rotations or the rotation angle of the motor 78 by means of a control device (not shown), depending on

the length of the 65th label.

  The members considered to be identical or equivalent, from the functional point of view or the embodiment point of view, to those of the preceding embodiment bear the same numerical references as those of the previous embodiment, but followed

  of a letter e, and the description of these bodies is not

  repeated. Subsequently, numerical references followed by a letter f, g, etc., will be used for

  identical or equivalent organs the description of which does not

will not be resumed.

  Figures 16 and 17 show a different embodiment of the label guide. This label guide 46f can be used, for example, in place of the label guide of the label feeding apparatus of FIG. 3. The label guide 46f comprises axial rods 91, 91 on which a number of rollers 92 are rotatably mounted. Each roller 92 is designed so that it can not fall from the axial rod 91 thanks to the presence of abutments 93, 94 fixed to the axial rod 91. The latter is connected by an accessory 96 to a piston rod 95a of a hydraulic cylinder 95 mounted on the base frame 2f and is moved up and down under the effect

  of the reciprocating movement of the piston rod 95a.

  The label is fed into the label feed apparatus including the label guide 46f when all the members operate in accordance with the sequence of operations as shown in FIG. 18. These operations, except for the motion vertical of the label guide 46f, are the same as those performed in the label feeding apparatus of Figure 3 (see Figure 5). When the web is advanced, the label guide 46f is in a raised position. Therefore, the band can go under

  the guide 46f of labels without encountering resistance.

  When the tape has been advanced and the retaining means retain it, the label guide 46f is lowered and rests on the tape. This is then cut into a label, then the driving element advances. Therefore, a label 65f remains resting on the label table by the label guides 46f. As a result, it is possible to prevent a label from accidentally slipping off the top surface of the label table. In this case, since the rollers 92 can rotate, the label 65f moves freely when the element

driving in advance.

  The label guide 46f is provided with a plurality of rollers 92. Therefore, when the label is narrow, only the rolls in contact with the label can rotate independently. The narrow label can

so be moved smoothly.

  Figures 19 and 20 show a third embodiment of the feed apparatus

  labels according to the invention. This device lg of food

  The label arrangement comprises a transfer means 21g whose construction differs from that of the means present in the label feed apparatus of FIG. 1. A feed rod 101 is rotatably supported by two bearings 22g, 22g. The rod 101 advance consists of a threaded rod. A movable member 102 is screwed onto the feed rod 101. One end of a link 103 is connected to the movable member 102. The other end of the rod 103 is inserted into a housing 11g through an opening 104 formed in the housing 11g and is connected to a reference sensor 18g. An advance rod 23g and the advance rod 101 are formed to have a right-hand thread and a left-handed thread of the same pitch, respectively. Gears 105 and 106 are mounted on the rods 23g and 101, respectively, to secure the two rods. Gear ratio - gear wheels

and 106 is 3: 1.

  This label feeding apparatus differs from the apparatus shown in Fig. 1 with respect to the connection between the marker detector 18g and a feed roller 16g. This relationship is described with reference to FIG. 21. In this example, if the marker sensor or detector 18g detects a mark 107 while the feed roll 16g is advancing a log band, the advance of the tape 10g is stopped. . Therefore, one can place the marker 107 in the exact position of a knife 17g by making the distance L4 between the knife 17g and the sensor 18g equal to the distance between two marks

adjacent 107.

  Since the feed rods 23g and 101 and the gears 105 and 106 are made as mentioned above in the label feed apparatus described above, the housing 11g and the sensor 18g are moved into the machine. same sense when the means 21g transfer is put into action. In addition, the ratio of the displacement distances of these elements 11g and 18g becomes equal to 1: 3. When the label feeding apparatus is used, the transfer means 21g is controlled according to the band used so that the distance between the marker detector 18g and the knife 17g can coincide with the spacing between the marks 107. The spacing between the driving element 31g and the knife 17g thus becomes automatically equal to half the distance between the marks 107 (the length of the label). In other words, the middle of the cut label is facing the element

depressing 31g.

  Examples of the shape of the end portion of the driving teeth are shown in Figures 22 and 23. In the example of Figure 22, the end portions 108 are formed on the upper ends of driving teeth 33h. . In the example of Figure 23, several needles 109 are provided at the upper ends of the driving teeth 33i. When these upper ends push the middle of the label, the tips 108 or needles 109 (penetrate) the label. As a result, the label can not

  to move away by sliding transversely.

  In Fig. 24, a folded hem forming means is shown as another example of the means for receiving the advanced label. This means is of a known type (for example that described in published Japanese Patent Application No. 59-46194) and includes a table 111, a folder 112, a rule 113, etc. The label 65j is carried by a holding member 6j and an end sewing portion 65aj is placed with respect to an already folded edge 114a of a fabric (eg a napkin) as shown in the figure. The edge 114a is folded upwardly on the ruler 113, in the form as shown in broken dotted lines, by the folder 112 moved in the directions indicated by arrows 116 and 117. After rule 113 has been removed , a

  part designated by the reference numeral 118 is sewn.

  An oblique movement of the holding member as shown in Fig. 25 or a circular motion centered at a point 120, as shown in Fig. 26, is possible in place of the aforementioned transverse movement. It goes without saying that many modifications can be made to the apparatus described and shown

  without departing from the scope of the invention.
