In an apparatus for bonding strip-shaped textile articles, especially pieces of outer fabric (10) and interlining strips (11), the textile strips (14) formed by bonding the latter are divided into individual textile units (15) after leaving a heating and pressure device (13). For this purpose, the textile strip (14) is severed in the region between successive pieces of outer fabric (10) by means of a cutting knife (31). This is controlled by a measuring light barrier with a transmitter (36) and a receiver (40). The measuring light barrier is designed so that it can be adjusted automatically to different light-transmitting capacities of the materials (interlining strip 11). |

DETAILED DESCRIPTION I claim: 1.
Apparatus for production of textile units comprised of sheet-like textile articles bonded to one another, in which strip-shaped outer fabric pieces are laid onto belt conveyed interlining fabric and, through heat and pressure from a heat and pressure means, are bonded to one another to form a continuous moving textile strip, wherein the textile strip, consisting of bonded textile pieces, is cut by a cutting apparatus in the interlining strip in the region between the successive pieces of outer fabric subsequent to the heat and pressure means, whereby the cutting apparatus is controlled through automatic sensing means (photocell), which senses the conveyed textile strips, thereby characterized, that regulating means (38/39, 41-43) are connected to sensing means (36/40) to provide for automatic adjustment of the sensitivity of said sensing means, and that said regulating means comprises a comparator (43), which compares the output voltage of the sensing means (36/40) with a signal generated by a peak value memory (41) controlled threshold signal generated (44).
2.
The apparatus of claim 1, thereby characterized, that the regulating means comprises said peak value memory (41) connected through a controller (42) to a variable amplifier (47), so that the peak output amplitude of the sensing means (36/40) is kept essentially constant.
3.
Apparatus according to claim 1, thereby characterized, that the sensor means (36/40), upon first sensing a textile strip, have sufficient startup data, particularly apparatus having a start light barrier (38/39) situated at a distance from the sensor means (36/40) for the initial setting of the sensor sensitivity of the sensor means (36/40) upon the first pass of the textile strip (14).
4.
Apparatus according to claim 3, thereby characterized, that the sensing means comprises a light measure barrier (36/40).
5.
An apparatus of claim 3, thereby characterized, that the start light barrier (38/39) is a reflection light barrier comprising a reflector (39) situated on the opposite side of the cutting conveyor belt (25)
