Abstract
Abstract Profiles or sectional shapes formed of elastic masses, especially rubber, are equipped with velour bands or tapes. The application of the velour bands is accomplished in the already formed profile which is still in a heated state, by slightly pressing the band carrier into the mass. The apparatus utilizes a guide element operatively associated with an injection disk or nozzle of an extruder, in order to deposit the velour band into the material at the extruder outlet. The profiles thus formed are used as sealing profiles in the window guides in the automotive industry.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
176 words
An apparatus for providing profiles formed of elastic masses with velour bands, said apparatus comprising: a guide element for guiding a velour band; means for forming a profile of a particular shape, said profile-forming means including means for heating the profile; said profile-forming means including an injection disc for forming and shaping the profile, and said guide element comprising an element mounted upon said injection disc; said guide element cooperating with said profile-forming means to define a path for feeding a velour band to cause the velour band to come into contact with a formed profile passing through said profile-forming means after the profile has been heated by said profile-forming means and while the profile is still in a heated condition; said path including throughpass means for passage of the combination of the profile and the velour band; and said throughpass means including a portion which is constricted in such a manner as to press a carrier band of the velour band into an outer layer of the profile which is still in a heated condition.
Claim 2
Independent Claim
176 words
An apparatus for providing profiles formed of elastic masses with velour bands, said apparatus comprising: a guide element for guiding a velour band; means for forming a profile of a particular shape, said profile-forming means including means for heating the profile; said profile-forming means including an injection disc for forming and shaping the profile, and said guide element comprising an element mounted upon said injection disc; said guide element cooperating with said profile-forming means to define a path for feeding a velour band to cause the velour band to come into contact with a formed profile passing through said profile-forming means after the profile has been heated by said profile-forming means and while the profile is still in a heated condition; said path including throughpass means for passage of the combination of the profile and the velour band; and said throughpass means including a portion which is constricted in such a manner as to press a carrier band of the velour band into an outer layer of the profile which is still in a heated condition.
Claim 3
Dependent Claim
20 words
The apparatus as defined in claim 1, wherein said guide element comprises fixed channel means for guiding the velour band.
Claim 4
Dependent Claim
36 words
The apparatus as defined in claim 11, wherein said guide element is so placed relative to said profileforming means as to feed the velour band into contact with the profile from a position above the profile.
Claim 5
Dependent Claim
28 words
The apparatus as defined in claim 1, wherein said injection disk has a recess formed therein, and wherein said element comprises an insert element received in said recess.
Claim 6
Dependent Claim
29 words
The apparatus as defined in claim 4, wherein said insert element comprises a portion cooperating with said injection disk to define fixed channel means for guiding the velour band.
Claim 7
Dependent Claim
26 words
The apparatus as defined in claim 4, wherein said insert element is adjustable relative to said injection disk, for adjusting said constricted portion of said throughpass.
Claim 8
Dependent Claim
25 words
The apparatus as defined in claim 1, wherein said guide element comprises a movable element for feeding the velour band into contact with the profile.
Claim 9
Dependent Claim
14 words
The apparatus as defined in claim 7, wherein said movable element comprises a roller.
