  • the needle number selected is counted out only when by means of a limit switch 202 (FIG. 1), a pulse has set a storage means, 67 over a lead-in 45, and a voltage is applied at a point 107. After the needle number selected has been counted, the storage means 67 receives a pulse over a conductor 179 and is reset.
  • next pulse over the conductor 45 is delivered from the switch 202 while the number of needles selected is still to be knitted.

As the counter 85 is at 1', the counter 86 is at 10', the counter 93 at 19' and the counter 97 at 28, or as the counter 85 is set at 12', the counter 86 is set at 21, the counter 93 at 30 and the counter 97 at 3. As the carriage runs in reverse direction, the counters count from 36 to 1.
  • a lead 10.3 runs from the connection point 1 to an AND-gate 69 while e.g., from the connection point 10' a lead 128 goes to an AND-gate 177 (FIG. 4), i.e., for each selection point 180, 181, 182 and 183 of a cam (FIG. 12).
  • the cam distance is selected in such a manner that each selection point 180, 181, 182 and 183 is in each case located on the sinker selected by its counter 85, 86, 93 and 97.
  • the selection point 180 is situated on a sinker corresponding to 1.
  • the counter 86 has selected 10' and the selection point 181 is situated on a sinker corresponding to 10.
  • the counter 93 is then at 19' and the selection point 182 on a sinker corresponding to 19 while the counter 97 is at 28', and the selection point 183 is at a sinker corresponding to 28'.
  • one of the conductors 74, 79, 81 or 83 must be currentcarrying.
  • the current is delivered over an OR-gate 75 and a lead 76 to storage means 1.85 which stores the pulse and transfers it over a lead-in 186 until over a lead 191 it is erased.
  • An amplifier 77 (FIG. 5) switches in over a conductor 78 all magnets corresponding to 1', i.e., all sinkers assigned a magnet corresponding to 1 project from the needle bed.
  • the selection point 180 at this instant is situated only on one of the sinkers chosen, and all other selection points 181, 182, and 183 are on other sinkers, the instantaneous selection is valid for this one sinker only.
  • FIG. 2 illustrates a detail pertaining to a selection point.
  • the carriage 163 runs with its guide 204 on a guide rail 205 over the needle bed 164.
  • Behind the needle bed 164 is located a control device with magnets 206 in form of electromagnets placed side by side, whereby the cores 207 of the magnets in each case either attract a retaining spring 208 when the magnet 206 as shown in the example is conducting current, or the spring is left under its own spring action.
  • the retaining spring 208 blocks a spring 209 which as the carriage passes through the pattern sinker 210 is pressed into the needle bed 164.
  • the leg 212 of the pattern sinker 210 is prevented from leaving the needle bed 164.1f, as shown in the example, the magnet 206 has been supplied with current, it holds the retaining spring 208 at its core 207.
  • the spring 209 pushes the pattern sinker 210 sufficiently high so that its leg 212 can be engaged by the cam 211.
  • the cam 211 pushes the pattern sinker 210 and with it the needle 213 upwards so that the needle 213 with its butt 214 can be engaged by the needle lifter 215 and can be made available for the knitting process.
  • the retaining spring 208 may also be provided with a permanent magnet which, at a given direction of the current through the coil of the magnet 206, is attracted by the core 207 of the magnet; and in the opposite direction of current through the coil, the retaining spring 208 is repelled.
  • the conductor 74 e.g., to carry current
  • the two lead-ins 63 and 73 must carry current.
  • the lead-in 63 carries current only if the leads 16 and 62 carry current. It thus becomes necessary that in the storage means 3 the storage position selected over one of the leads 6-15 at the point sampled by the master clock 1 has a stored signal which is transmitted over the lead 16, and that a signal is applied at the OR-gate 66. This is the case if in the storage means 31 the storage position selected over one of the control leads -30 is provided with a stored signal at the point sampled by the master clock 1 which signal is transmitted over the lead 32.
  • the signal is forwarded by the INHIBITORY-AND-gate 65 to the lead 61 only if at the same time no voltage is applied to one of the two, or both, conductors 46 and 60.
  • the INHIBITORY- AND-gate 65 is locked, regardless of whether or not a signal is applied at the output 32.
  • the control tape 184 transferred the data to the temporary storage 50. If now a pulse from the master clock 1 encounters a stored signal, the signal is forwarded over the conductor 51. If then no signal is applied to the conductor 46, the previous signal on the conductor 51 is forwarded through the lNHIBITORY-AND-gate 152 and the lead-in 153 to the OR-gate 66. In the event that now in the storage means 38 one of the storage positions is tapped by one of the control leads 41-44, voltage is applied at the same time in point 107. If there arrives a signal from the master clock 1 to a storage position, the storage means 38 forwards the signal over the lead 46.
  • the lead blocks the INHIBITORY-AND-gates 65 and 152 but forwards its signal to the OR-gate 66. Thereby current flows in the lead-in 62, regardless of whether or not a' signal comes from the leads 32 and/or 51.
  • the data of the storage means 57 have priority over the data of the storage means 31 and those of the storage means 38 have priority over the data of the storage means 31 and 50.
  • the lead-in 191 for erasing receives its current from a counter 194 which is continuously stepped up by the master clock 1 over the lead 2 but always delivers signals through four outputs. If the counter is at 1, the counter 86 at 10', the counter 93 at 19' and the counter 97 at 28', the counter 194 is at 6', 15', 24', and 33, whereby the lead 192 goes from the connection point 10' to a storage means 187 (FIG. 4). Thus, if a magnet for holding is cut in, it remains attracted until the carriage has advanced over five needle division spaces. Then the magnet has time to drop until the carriage has advanced over four more needle spaces.
  • all four outgoing signals are stepped up by one after each needle space, i.e., from 6, 15, 24 and 33 to 5', 14', 23' and 32', and on the reverse direction of the carriage to 7', 16, 25' and 34, etc.
  • switching may also be effected in such a manner that on shifting of the storage means 185, current-is delivered in the opposite direction, e.g., to the coils of the magnets 206 of the magnet group corresponding to 1, by means of an amplifier 240 over a lead 241, so that the springs 208 with permanent magnets are repelled by the core of the magnet 207.
  • the magnet group corresponding to 10' is provided in the first group for selection position 180, whereby instead of the AND- gate 69, and AND-gate 177 is provided which while also being acted on by the conductor 71 from the storage 68, is also controlled by the conductor 128 from the connection point 10' of the counter 85.
  • the AND-gate 64 is controlled, exactly as for the magnet group corresponding to 1', by the conductors 16 and 62.
  • a conductor 132 delivers current through an OR-gate 133 if a voltage is applied to an AND-gate 178 over the leads 63 and 244.
  • the storage means 187 is set up and delivers a signal, over a conductor 188 and an amplifier 135 which over the conductor 136 cuts in the magnet group corresponding to 10' (FIG. 5), until it is erased by a conductor 192. This is obtained when the counter 194 is set at 1, 10, 19, and 28'.
  • the various magnet groups corresponding to 1 to 36 are controlled in relation to each of the selection positions 180, 181, 182 and 183 by means of various connections or linkings.
