~ ig. 19 sllows a cable tree made by mealls oE the apparatus, and Figs. 15 to 20 illustrate various wrapping steps leading to the production oE the cable tree of Fig. 1~.
Fig. 1 illustrates an apparatus 1 with an electronic program control unit 2 which comprises a dis]~ drive 3, an input keyboard 9 and a display 5 and which is connected by means of a mounting 6 with various drive components of the apparatus 1. The apparatus 1 also comprises a Eeed mechanism 7 which includes, on its one side, a feed carriage ~ with a holder 9 ~or holding the elongate objects, and on the other side, two vertically movable rollers 10, 11 disposed vertically one above the other.
The axes of rotation oE the rollers are disposed transversely to the longitudinal axis of the objects. One roller 10 functions as a Eeed length data detector 10' and the other roller 11, as a feed drive 11'. The carriage 8 is movable in parallel to the axis of rotation of a wrapping wheel 12 or :to the longitudinal axis of the objects. The wrapping wheel 12 is disposed on the right hand side of and inlthe vicinity of, the rollers 10, 11 and is equipped with a tape spool support 13 and enclosed with a safety cover 14. Near the wrapping wheel 12 on its right ha:nd side is provided a supply chànnel 15 for ~eeding the elongate objects to the:apparatus. Between the rollers 10, 11 and the wrapping wheel 12 is disposed a tape cut-off device 16 -~ B~ ~adapted to cu~ oEE the tape closely to tlle objec~s a~ tlle elld of the wrapping operation ar at the end of the tape stock l7.
At~:the stock tape spool support 13 is provided a stock tape control device 18 which serves the purpose of automatic term~lnation of~the wrapping operation just before the~ end of the stock~tape l7. The~operatlon can then be resumed with a~new~ stock tape 17 according to the program. ~
Fi~g. 2~is a side view of the feed mechanism 7 in a beginning-oE-wrapping position. In this position, the feed carri~age ~ with the holder:9 is moved from its leEt, resting position 19, marked with bro]cen~line, into the wrapping wheel 12, : :

the beginning of the objects 20 being secured to the holder 9.
one side adhesive tape 2L is particularly suitable Eor the wrapping. In this s-tarting position, the rollers 10, 11 are spaced apart so much that they do not hinder the carriage 8 being moved therebetween to the starting position.
Fig. 3 shows a plan view oE the feed mechanism 7 of Fig. 2.
Yor programmed holding oE tlle objec~s 2~ ~y mcalls ~r ~l~e l~ol~er 9, the latter is operatively connected with a controlled actuating cylinder 2~ whereby the holder 9 is controllable as well. ~s indicated witll bro]cen lines, -the roller 11 is connected with a motor 23 to which the Eeed carriage 8 is also connec-ted by way of a controlled coupling 29. The motor 23 can work simultaneously as a displacement piclcup drive 23'. In order to enable -the prese-t displacement -to be controlled or measured, the feed carriage 8 may be provided with a digital scale 25 which corresponds with the control system 2 by way oE an op-tical sensor.
Following the withdrawal of the carriage 8 ~ith the objects 20 from the area of the rollers 10, 11 and the wrapping wheel 12, rollers 10,11 are brought together so that they come into con-tac-t with the objects 20, wherein the roller 10 functions as data detector lO' and the roller 11, as feed drive ll'. In -this position, shown in Fig. 9, both rollers 10, 11 or the feed drive 11' respectively, along wi-th -the feed carriage 8 run synchronously in the direction of the arrow 26 at the feed velocity.
A plan view of the feed mechanism 7 of Fig. 9 is shown in Fig. 5.
When the carriaye 8 reaches its maximum travel length and the objects 20 are still not wrapped in full length, the program wi~ cause ~the actuating cylinder 22 to release the holder 9. This will result in~the objects 20 sayging and their feed being overtaken en-tirely by -the feed drive 11', as shown In ~Fig. 6. ~ ~;

which in its passive position (Fig. 9) is disposed outside the wrapping wheel 12. This position 27 is illustrated in Fiy. 8.
For cutting off the wrapping tape 21, the device 16 is brought into the position marlced with bro]cen line,by means of a piston cylinder 28. Fig. 9 represen-ts a plan view of this position.
Next, the cut~oEf device 16 is brought further into the marlced position by means of a piston cylinder 29. The tape 21 is now located in a slit 30. A knife 32, disposed at right angle to the tape and pivotable about an axis 31 is positioned near the slit 30. The knife 32 is ac-tua-ted by a piston cylinder 33. Due to the rotation oE the ]cnife 32 abou-t the axis 3l, the tape 21 can be cut more reliablyr Following the cutting, the device l6 is brought into the passive position 27 (Fig. 3) by means oE
the control unit 2 in the reverse sequence X~M~nC~ of steps.
Figs. 10 and 11 illustrate a stoclc tape control device 18 with an attachment 34 for measuring -the minimum diameter oE
the tape spool. The attachment 34 serves to stop the wrapping operation by way of a lever mechanism 35 when a preset minimum diame-ter of the tape spool is reached. The diameter of the spool is cletected by~a roller 36. Depending on the spool diameter, the lever 37 is moved about a fixed axis 38. ~ever 37 is connected with lever ~0 via an axis 39 so that as a result oE -that motion, lever 90 is swung about a Eixed axis 41, as shown in Fig. ll.
This in turn causes a sensing lever 42 to fall into a recess 43 when the preset minimum spool diameter is reached. The lever 4~2 in this position act~ivates, with its other end, an approach switch 44 which in turn causes the wrapping procedure to end via the control unit 2. ~n (al-ternative) contactless stock tape control device 18 (Fig. 12 - transl.) operates by means of a light barrier 45, wherein a light~transmitter 47 is d~is~posed on one~ side of~khe t~ape spool 46 and a light receiver 4B~ s m~ounted~on~ the other side, -t~he latter performing the same function as~thé switch~44.

signal lines 51. In the logical system of the apparatus 1, the program control unit 2 is linked with a pneumatic generator 52, mo-tors 23,53 and the stoclc tape control device 18. Further, a rota-tion transmit-ter 59 is provided which synchronizes the pre-set rotational speed of the wrapping wheel 1.2 wit~ the ~eed mechanism 7 by way of the motor 23, for which purpose a path length (scale) data detector 25' and the Eeed length da-ta detector 10' are employed.
The wrapping procedure will be explained in more detail by the example of a wiring harness, or cable tree 55 according to ~ig. 1~. The arrows marlced wi~l1 one numeral indicate the sequence and direction of wrapping procedure. The values Xl to X6 represent the respective wrapped lengths, while Yl to Y4 indicate the lengths to be left unwrapped.
Figures 15 to 20 illus-trate the particular manual and programmed operation steps. The symbols in rectangles indicate the respective program data shown on display 5.
~: According to Fig. 15, -the beginning of a one-side adhesive tape 21 is applied onto the beginning of the cable : tree 55 (first operation step l). Next, the wrapping wheel 12 is enclosed with a safety cover (not illustrated~) and the wrapping :procedure begins with the display showing 0 mm and ends after the wrapping:length reaches 1190 mm (=Xlj, whereupon the tape 21 is cut oEE~automatically with the tape cutting device 16.
: In a second step 2 the cable tree 55 is advanced in the directi;on of~arrow by 180 mm (=Y~ t -this point,:~the saFety cover opens automatical:ly to enable -the beginning oE the tape to be~placed manually on the cable tree (Fig~. 16).

3. The apparatus (1) according to claim 2, characterized in that the feed carriage (8) is provided with a displacement pickup drive (23').
4. The apparatus (1) according to claim 1, 2 or 3, characterized in that the feed drive (11') is activated by a control system (2) which releases the beginning of the objects (20) from the holding means (9).
5. The apparatus (1) according to claim 1, 2 or 3, characterized in that the tape spool support (13) is provided with a stock tape supply control device (18).
6. The apparatus (1) according to claim 5, characterized in that the device (18) is provided with an attachment (34) for measuring the minimum diameter of the tape spool and stops the wrapping procedure when a predetermined minimum diameter of the spool is reached.
7. The apparatus (1) according to claim 5, characterized in that the measuring of the minimum diameter is effected by means of a lever mechanism (35) or a light barrier (45).
8. The apparatus (1) according to any one of claims 1 to 3 and 6, characterized in that it further comprises a tape cut-off device (16).
9. The apparatus (1) according to claim 8, characterized in that the cut-off device (16) has a slit (30) for receiving the tape (21) to be cut off, and a pivotable knife (32) disposed at a right angle to the tape (21).
