Claims

1 2 Claims · intended to measure the length of several workpieces lying next to one another on a table

1. Device for length measurement of rod (German utility model 1 932 865).
Shaped material, in particular pipes, so-called measuring cable devices are also known, with several pipes of different lengths - on 5 with a stop on a table next to one another for measuring a pipe and on a connection device to one end of the pipe and the one to be knocked out, thereby The marked tape measure is placed next to the other. On net that a measuring ruler (2) across the to the device can then the measured length is arranged on a measuring tube, which can be read by a counter and optionally printed on a rope (12) with the rotor part of a length sensor io paper strips. However, this length (5) measurement via an attached measuring drum (4) is very cumbersome and time-consuming, and that a stop (8) that can be displaced in the longitudinal direction of the pipes because the measuring device is applied to each individual pipe must be used and at least two operators are arranged, who via a rope (9) with the requires (German Auslegeschrift 1023 892 and stator part of the length transmitter (5) via a US patent 2 553 613).
